No. of bitstreams: 1 Eduardo Soares da Costa Faro.pdf: 3139532 bytes, checksum: 8e1a3a586ef05a1c4cd4efa988b69ec5 (MD5) Previous issue date: 2007-12-03 / While setting the principles of the public managerial model, little energy was deposited in understanding the needs and values of civil servants. Many agreed that the managerial model would be a feasible way to increase the efficiency of the public organizations, but would the civil servants be willing to adopt its practices and underlying values and behaviours? Would they recognize the value of the rewards offered by these new careers? And still, would they abdicate from the traditional rewards that were conquered after decades in a bureaucratic career? These questions lead us to the discussion of the implications of the needs and values of civil servants in the implementation of managerial practices. One way of understanding this relationship is through the study of the career anchors and how they relate to the organizational career management model. For such, a case study at the Brazilian Court of Auditors Tribunal de Contas da União (TCU) was conducted, with the objective of deepening the comprehension of the implications of civil servants career anchors in the implementation of managerial practices. The result of the survey identified that the intention of adopting these practices will have to face three main obstacles. The first refers to the incompatibility between the desire of overcoming a bureaucratic model and the presence of a career management model that, fundamentally, satisfies the needs of typical bureaucratic individuals. This obstacle suggests the need for interventions in the career management model characteristics, so to reward managerial behaviours and not only those associated with security. The second obstacle refers to the apparent incompatibility between the behaviours and values advocated by the managerial model and the career anchors of TCU s civil servants. The overcoming of this obstacle will require some degree of integration between TCU s need to implement these practices and the needs and values of it s civil servants. The third obstacle is in the incompatibility between the civil servants career anchors and the rewards emphasized by the current career management model. This obstacle suggests the presence of a perception of career stagnation among the civil servants, what could impact upcoming intervention initiatives in TCU s career management model. The understanding of these obstacles can contribute to the discussion about the construction of these new careers and the role of the civil servants in the context of the modernization of the public civil sector / Ao serem propostos os princípios do modelo de administração gerencial pouco se aprofundou sobre as necessidades e valores dos servidores públicos. Muitos concordaram que a administração gerencial seria um caminho viável para o aumento da eficiência e eficácia das organizações públicas, mas estariam os servidores dispostos a adotarem estas práticas, valores e comportamentos subjacentes? Reconheceriam eles o valor das recompensas que seriam oferecidas por estas novas carreiras? E ainda, estariam eles dispostos a abrir mão de recompensas tradicionais conquistadas após décadas em uma carreira burocrática? Estas questões nos levam à reflexão sobre as implicações das necessidades e valores presentes entre servidores públicos para a implementação de práticas gerenciais. Uma forma de compreendermos esta relação é por meio do estudo das âncoras de carreira e como elas se articulam com o modelo de gestão de carreiras. Para tal, foi realizado um estudo de caso no Tribunal de Contas da União (TCU) com o objetivo de aprofundarmos o estudo das implicações das âncoras de carreira dos servidores no contexto de implementação de práticas do modelo gerencial. Como conclusão da pesquisa foi identificado que a intenção de adotar estas práticas deverá enfrentar três obstáculos. O primeiro refere-se à incompatibilidade entre o desejo de superação de um modelo burocrático e a presença de um modelo de gestão de carreiras que, fundamentalmente, enfoca a satisfação das necessidades de indivíduos típicos de um modelo burocrático. Este obstáculo sugere a necessidade de que sejam efetivadas intervenções nas características do modelo de gestão de carreiras, de forma a recompensar comportamentos mais gerenciais e não somente associados à segurança. O segundo obstáculo refere-se à aparente incompatibilidade entre os comportamentos e valores preconizados pelo modelo de administração gerencial e as âncoras de carreira dos servidores. A superação deste obstáculo irá requerer algum grau de integração entre a necessidade do TCU em implementar estas práticas e as necessidades e valores dos servidores. O terceiro obstáculo está na incompatibilidade entre as âncoras de carreira dos servidores e as recompensas enfatizadas pelo modelo de gestão de carreiras. Este obstáculo sugere a presença de uma percepção de estagnação na carreira, podendo dificultar iniciativas de intervenção no modelo de gestão de carreiras do TCU. A compreensão destes obstáculos pode abrir caminhos para a reflexão sobre a construção destas novas carreiras e o papel dos servidores no contexto da modernização do setor público

I rapporten har vi skrivit om naturstenens roll och förutsättningar som fasadmaterial inom byggproduktion. Målet med undersökningen var att belysa nya tekniker som finns på marknaden. Metoder som har använts för att undersöka infästningstekniker är genom intervjuer och studiebesök.   Den stora frågan var att ta reda på hur dem nya teknikerna kan påverka vår arbetsmiljö, miljö samt estetik. En annan fråga var hur den nya tekniken kan uppfylla de nya kraven?   Natursten är ett naturligt material som är inhomogen och därför förekommer det färgskiftningar och variationer i stenskivorna. En beställare ska därför vara väldigt specifik när stenen utses.   Det finns en stor risk med att förankra stenskivor utan mekanisk förankring. Utan förankringen kan stenen lossna från fasaden. Idag bygger vi vanligen med tekniken ventilerad luftspalt, mellanrum mellan stenskivor och stomme. På det sättet kan alla stenskivor röra sig utan spänningar samtidigt som luftspalten ventilerar och dränerar ut fukten bakom stenskivorna. Genom att välja lämpliga stendimensioner och ankare i standardutförande kan kostnaderna minskas. Denna rapport tar upp ny teknik. FZP, Fischer Zykon Panel, är ett undercut ankare. Detta är en valmöjlighet om en beställare vill erhålla skivor som är 20 mm i tjocklek.   Björn Shouenborg har designat ett program som gör det möjligt att dimensionera sten på fasader. Programmmet visar om dimensioneringen är ok med hänsyn till säkerhetskraven.   Med tanke på de stora miljökraven som ställs är det både lönande att undersöka möjligheter och ny teknik. Stommen byggs med mer isolering vilket kräver en längre expanderbult eller ankare mellan stenen och stommen.   I denna rapport framkommer det att en arkitekt och stenentreprenör är positiva till ACT-systemet.  Den här rapporten har belyst att den nya tekniken har en positiv påverkan på arbetsmiljön, miljön, estetik och tid. / The report talks about the capacity and conditions as a façade material within building construction. The goal with the research was to shed light on the new technique available today.  The methods used to examine the mechanical anchoring techniques were through interview and fieldstudies. The main question was to find out how those new technologies can affect our health and safety, environment and aesthetics. Another question is how the new technology can meet the new requirements?   Natural stone is a natural material that is inhomogeneous and therefore there are color variations and variations in stone tiles. A client should therefore be very specific when the stone is appointed. There is a great risk to anchor stone tiles without mechanical anchoring, without it the stone can detach from the façade. The technology most commonly used in anchoring stone is using a ventilated air gap, a space between the stone tiles and facade. In this way, all stone tiles move without tension and furthermore the air gap ventilates and drains the moisture behind the stone tiles. It is possible to cut costs by choosing the appropriate stone dimensions and tiles in the standard execution. New technology opens up new possibilities. An alternative is FZP, Fischer Zykon Panel which is an undercut anchor. This could be used as an option if a client wishes to have 20 mm thick tiles. Bjorn Shouenborg, researcher, has designed a program that makes it possible to dimension stone facades.The software that shows if the design is ok with regard to safety requirements.   Given the large environmental requirements imposed today, it is conceivable both be worthwhile to explore the possibilities and new technologies. The façade is built with more insulation which requires a longer expansion of anchors.   In this report, it appears that an architect and stone contractor is positive for the ACT system. This report has highlighted that the new technology has a positive impact on the work environment, the environment, aesthetics and time.

For this purpose an extensive experimental program was conducted at the Structural Materials Laboratory of the Civil Engineering Department at the University of Patras. A total of 18 identical rectangular reinforced concrete columns were constructed in a scale of 3/5 and 770 mm height so that the slenderness effects could be eliminated and tested in uniaxial compression. The columns were separated in two groups according to their aspect ratio; the first group consisted of seven RC column specimens with cross section dimensions 150mm by 450mm and an aspect ratio equal to 3, and the second group consisted of eleven RC column specimens with cross section dimensions 150mm by 600mm and an aspect ratio equal to 4. To facilitate FRP and TRM wrapping, the four corners were chamfered with a radius equal to 20mm. A number of parameters were investigated such as the kind of the matrix material (organic and inorganic), the number of layers of the jackets (1, 2, 3 and 4), the role of different cross section aspect ratios (3 and 4), the effectiveness of spike anchors (resin-impregnated fiber rovings) and local strengthening with U shape jacketing placed at the smaller sides of the columns. The first chapter provides general information on FRP materials describing their individual components, their characteristic properties, the factors affecting their behavior as well as the basic techniques for their application. The second chapter describes the composite materials in inorganic matrix (TRM) and presents a comparison between the two composite material strengthening systems. In the third chapter a brief literature review is provided about the confinement of columns with conventional techniques (e.g. steel plating, steel jacketing, RC jacketing) as well as with composite materials. The constitutional law of confined concrete with jackets of composite materials is described. Furthermore some experimental studies from the international literature are presented concerning the effectiveness of the confinement with FRP jackets of columns with small and high aspect ratio. Finally, the chapter concludes with a brief reference to experimental studies on specimens confined with jackets in inorganic matrix (TRM jackets). The fourth chapter presents the procedure for constructing and retrofitting the specimens including the materials used (carbon fiber fabric and textile, carbon fiber spike anchors, epoxy resin, inorganic matrix) as well as the equipment used for uniaxial compression tests. In the fifth chapter the results for each specimen are given presenting their failure mode and the corresponding load - displacement curve. In the following chapter the results for each group are compared in order to establish general conclusions on the effect of the kind of the matrix material, the number of layers and the existence of FRP anchors in confinement of wall-like RC columns. The seventh chapter presents the results of an analytical model used to predict the maximum compressive load and the ultimate deformation of specimens confined with FRP or TRM jackets. A comparison between the experimental and the analytical results is made and it is examined whether this model can be used for columns with high aspect ratio after modifying some of the parameters. The eighth chapter summarises the most important conclusions of all investigations carried out by the present project for both the experimental procedure and the analytical model. Finally, some suggestions for further research on columns with high aspect ratio are listed.

Helical anchors, used widely to resist uplift loading for a variety of applications, including in transmission towers, pipelines, offshore structures, etc., are subjected to environmental cyclic loads that influence the anchor performance and may induce fatigue failure. However, the influence of cyclic loading on helical anchor behaviour is unknown. A comprehensive evaluation of the effect of cyclic loading on the load-displacement response of single-helix anchors in sandy soils is presented here, including an interaction diagram to help designers evaluate the impact of different conditions in cyclic loadings. The experimental work of this thesis includes geotechnical centrifuge modelling and field load tests. The centrifuge model tests were carried out with reduced scale models of helical anchors in sand, at IFSTTAR (Nantes, France). The field load tests were performed on helical anchors installed in a tropical residual soil of the Experimental Site of the University of São Paulo (São Carlos, Brazil). In addition, numerical modelling was used to predict the pre- and postcyclic responses of the single-helix anchors tested in a centrifuge. The main findings of this research are: (a) helical anchor behaviour is governed by helix bearing resistance, and no loss of helix bearing capacity was observed in the range of cyclic loadings tested, (b) the degradation of shaft resistance was noticed mainly during the first 100 cycles, when the accumulation of permanent displacements is more significant, (c) an interaction diagram showing the different conditions of cyclic stability is proposed from the results of the experimental data, (d) modified values of the bearing capacity factor in tension (Nq) are suggested for the estimation of post-cyclic uplift capacity of single-helix anchors in sand, (e) the installation effect of the anchor should be taken into account in the numerical model in order to obtain reliable predictions of the helical anchor performance. / As estacas helicoidais são largamente utilizadas para resistir a carregamentos de tração em uma variedade de aplicações como torres de linhas de transmissão de energia, dutos enterrados, estruturas offshore, etc. Estes tipos de estruturas são normalmente submetidos a carregamentos cíclicos que influenciam o desempenho de fundações por estacas helicoidais submetidas a esforços de tração, e podem induzir ruptura por degradação da capacidade de carga. Contudo, a influência do carregamento cíclico no comportamento das estacas helicoidais (ou ancoragens helicoidais, quando submetidas apenas a esforços de tração) é pouco conhecida. Uma avaliação abrangente do efeito de carregamentos cíclicos sobre o comportamento das ancoragens helicoidais é apresentada nesta tese, incluindo um diagrama de interação para auxiliar na avaliação do impacto de diferentes condições de carregamento cíclico. O trabalho experimental desta tese inclui modelagem em centrífuga geotécnica e ensaios de carregamento cíclico em estacas na grandeza real em campo. Os ensaios em centrífuga foram realizados com modelos reduzidos de estacas helicoidais em areia, no IFSTTAR (Nantes, França). Os ensaios de campo foram realizados em ancoragens helicoidais instaladas no solo residual tropical do Campo Experimental de Fundações da Universidade de São Paulo (São Carlos, Brasil). Além disso, modelos numéricos foram utilizados para simular os resultados do comportamento das ancoragens helicoidais ensaiadas em centrífuga nas condições pré- e pós-ciclos. Os principais resultados desta pesquisa são: (a) a capacidade de carga à tração da ancoragem helicoidal é controlada pela capacidade de carga da hélice, (b) a degradação da resistência por atrito lateral foi observada principalmente durante os primeiros 100 ciclos, período em que a acumulação dos deslocamentos permanentes é mais significante, (c) um diagrama de interação mostrando as diferentes condições de estabilidade cíclica é proposto a partir dos resultados experimentais em centrífuga, (d) valores modificados do fator de capacidade de carga em tração (Nq) são sugeridos para estimativa da capacidade pós-ciclos de ancoragens helicoidais com uma hélice em areia, (e) o efeito da instalação da ancoragem deve ser levado em consideração no modelo numérico para que se obtenha previsões confiáveis do desempenho de ancoragens helicoidais.

Ancoragens são muito utilizadas na estabilização do maciço rochoso pela rapidez e baixo custo, embora sua análise não seja completamente entendida devido à interação de diferentes materiais como rocha, graute e aço. Este documento apresenta os resultados de um estudo realizado em juntas lisas reforçadas com ancoragens. Foram ensaiadas ancoragens com barras de diferentes diâmetros e diferentes orientações em relação ao plano da descontinuidade. Os ensaios realizados para avaliar o comportamento deste tipo de reforço foram o ensaio de arrancamento em tubo duplo e o ensaio de cisalhamento em juntas lisas reforçadas. Os ensaios de arrancamento em tubo duplo demonstraram que a resistência ao arrancamento é dependente da resistência à tração da barra. As deformações internas no sistema foram idealizadas através da obtenção de um comprimento livre hipotético de uma barra livre submetida a tração. Nos ensaios de cisalhamento, avaliou-se a melhora da resistência ao cisalhamento de descontinuidades lisas reforçadas com barras ancoradas. Observaram-se dois picos de carga mobilizada antes da ruptura do sistema no caso de barras perpendiculares ao plano da descontinuidade. Este fato introduz significativa ductilidade ao sistema e é importante do ponto de vista de confiabilidade do sistema. A ruptura das ancoragens se produz devido a uma combinação de efeitos de tração, flexão, e cortantes. Os sistemas reforçados com áreas maiores de aço apresentaram maior ductilidade, e, portanto oferecem maior segurança. Os resultados sugerem que uma vez superado o comprimento mínimo ancorado a ruptura das ancoragens acontecerá por ruptura das barras de aço e não por aderência na interface barra-graute, concluindo-se que a resistência das ancoragens é dependente da resistência de ruptura e da área de aço utilizada. Finalmente, esta pesquisa contribui ao entendimento dos mecanismos de ruína que acontecem num maciço reforçado com ancoragens. / Rock anchors are widely used to stabilize rock masses due to their rapid installation and low cost. Their behavior is not fully understood because of the interaction of different elements such as rock, grout and steel. This document presents the results of both pull-out and shear tests on steel bar reinforced discontinuities. Tests were carried out with different diameters and orientations of bars with respect to the discontinuity plane. Double-pipe pullout tests and smooth-joint anchor-reinforced shear tests were performed. The results of double-pipe pull-out tests were analyzed in terms of both strength and deformations. Internal strains were idealized through a model based on hypothetical length of a free bar. In the smooth-joint anchor-reinforced shear tests, both increase in shear strength and ductility were evaluated. Two load peaks were observed in test with bars perpendicular to the joint plane. Ductility is significantly increased with respect to joints reinforced with inclined bars. This is important for reliability evaluation. The failure of anchors is produced by a combination of tensile, bending, and shear internal forces. The systems reinforced with a greater amount of steel presented more ductile behavior than those less reinforced. The results suggest that since the minimum anchor length is exceeded, the system failure is governed by the rebar failure and not by the adhesion in the rebar-grout interface. From this, it is concluded that the anchor strength is dependent on the strength and cross section area of the rebar. Finally, this research contributes to better understanding of the failure mechanisms of anchor-reinforced rock masses.

This construction is used to built underground parts of the building. The last part of the work contains description of technological proces of the geotechnics constructions execution. The drawing documentation is also included.

The topic of this master's thesis are the design of ensuring foundation pit and foundation of administrative building in Prague. In the vicinity of foundation pit is situated the river Vltava, which directly influences the ground water level at the job site. During construction, it is necessary to envisage the possibility of occurrence of the old building structures of docks.

The aim is to design economical and above all safe securing a deep notch, both in the construction phase and throughout the use of the building. In the first part of the thesis Background research will be given an idea of the construction of the geotechnical point of view. The second part will contain the geotechnical design calculation. The third part will be proposed safety recommendations in terms of geotechnical monitoring.

Face à la mondialisation et à une demande accrue de ressources humaines hautement qualifiées, les pays en voie de développement, en général, font face à une mobilité internationale de leurs professionnels de la santé vers les pays développés. L’objectif de cette thèse est d’étudier les déterminants des intentions liées à la mobilité internationale des professionnels de la santé d’origine étrangère (hors U.E) résidant en France. À cet effet, un modèle de recherche a été élaboré à partir de la théorie de l’adaptation interculturelle et des travaux conduits sur le management des carrières et la théorie des ancres de carrières. Notre recherche prend ainsi en compte trois grandes composantes : (i) l’adaptation interculturelle (au travail, à l’interaction, et générale), (ii) le plafonnement de carrière structurel et la satisfaction dans la carrière, et enfin (iii) le rôle des ancres de carrière principalement les ancres de « stabilité géographique » et « internationale ». Il s’agit de préciser l’incidence de ces 3 composantes sur l’intention (a) de retour au pays d’origine, (b) de partir dans un pays tiers, (c) de rester en France. À la suite d’une revue de la littérature, des hypothèses de recherche ont été émises. Les données ont été collectées, par questionnaires, auprès des professionnels de la santé d’origine étrangère résidant en France (PSOE). Les analyses statistiques ont été effectuées sur un échantillon de 317 réponses. Les principaux résultats obtenus montrent d’une part que l’adaptation interculturelle en France n’a pas un effet significatif ni sur l’intention de retour au pays d’origine, ni sur l’intention de partir dans un pays tiers. Par contre, l’adaptation à l’interaction a un effet significatif et positif sur l’intention de rester en France. D’autre part, le plafonnement de carrière structurel est significativement et positivement associé à l’intention de retour au pays d’origine et à l’intention de partir dans un pays tiers. On notera que la satisfaction vis-à-vis de la carrière est seulement significativement reliée à l’intention de rester en France. La justice organisationnelle distributive a quant à elle une influence significative et positive sur l’adaptation générale et sur le sentiment de satisfaction dans la carrière, et d’autre part un effet négatif et significatif sur le sentiment de plafonnement de carrière structurel. Nos résultats soulignent enfin l’influence des ancres de carrière sur les intentions liées à la mobilité internationale. Des variables de contrôle d’ordre sociodémographique, décisionnel, et contextuel jouent également un rôle dans la dynamique de la mobilité internationale des PSOE. Les résultats obtenus nous ont permis de dégager, entre autres, des implications managériales et pratiques susceptibles d’encourager, d’une part, le retour des PSOE dans leur pays d’origine mais aussi leur maintien en France. Des limites et des perspectives futures de recherche sont également soulignées dans la conclusion. / In the context of globalization and a growing demand for highly qualified human resources, many healthcare professionals from the developing countries are now moving on their own initiative to the developed countries. The purpose of this thesis is to examine the determinants of international mobility intentions among foreign-born (outside the UE) healthcare professionals living in France. In this respect, we have built a research model based on the research on careers management and the theories related to cross-cultural adjustment and career anchors. Our research takes into account three main dimensions: (i) cross-cultural adjustment (to work, to interacting with host nationals, and to the general environment), (ii) hierarchical career plateauing and career satisfaction, and (iii) the role of career anchors, specially «geographical stability» and «internationalism». In fact, we seek to clarify the influence of each of these three dimensions on the intention (a) to return to the country of origin, (b) to go to another, (c) to stay in France. Following a review of the literature, research hypotheses were formulated. Data was collected, by questionnaires, from foreign-born healthcare professionals living in France. Statistical analyses were based on a sample of 317 responses. The main results show, on the one hand, that cross-cultural adjustment in France has no significant effect neither on the intention to return to the country of origin nor on the intention to go to another country. However, interaction adjustment has a positive and significant effect on the intention to stay in France. On the other hand, hierarchical career plateauing is positively and significantly related to the intention to return to the country of origin and to the intention to go to another country. It should be noted that career satisfaction is significantly related to the intention to stay in France. Distributive justice, for its part, has a positive and significant influence on general adjustment and career satisfaction but has a negative and significant effect on hierarchical career plateauing. Finally, our results underline the influence of career anchors on the intentions related to international mobility. When it comes to control variables, we see that personal characteristics, decision-making aspects, and contextual elements play a role in the international mobility dynamic of the foreign-born healthcare professionals living in France. Based on our results, we have formulated managerial and practical implications that could encourage the foreign-born healthcare professionals to return to their country of origin but also to stay in France. Limitations and vision statement for the future research are underlined in the conclusion.
