The present work describes the finite element (FE) modeling and dynamic response of lightweight, deployable shelters (tent) to large external blast loads. Flexible shelters have been used as temporary storage places for housing equipments, vehicles etc. TEMPER Tents, Small Shelter System have been widely used by Air Force and Army, for various field applications. These shelters have pressurized Collective Protection System (CPS), liner, fitted to the frame structure, which can provide protection against explosives and other harmful agents. Presently, these shelter systems are being tested for the force protection standards against the explosions like air-blast. In the field tests carried out by Air Force Research Laboratory, it was revealed that the liner fitted inside the tent was damaged due to the air blast explosion at some distant from the structure, with major damage being on the back side of the tent. The damage comprised of tearing of liner and separation of zip seals. To investigate the failure, a computational approach, due to its simplicity and ability to solve the complex problems, is used. The response of any structural form to dynamic loading condition is very difficult to predict due to its dependence on multiple factors like the duration of the loading, peak load, shape of the pulse, the impulse energy, boundary conditions and material properties etc. And dynamic analysis of shell structures pose even much greater challenge. Obtaining solution analytically presents a very difficult preposition when nonlinearity is considered. Therefore, the numerical approach is sought which provide simplicity and comparable accuracy. A 3D finite element model has been developed, consisting of fabric skin supported over the frames based on two approaches. ANSYS has been used for obtaining the dynamic response of shelter against the blast loads. In the first approach, the shell is considered as a membrane away from its boundaries, in which the stress couple is neglected in its interior region. In the second approach, stress coupling is neglected over the whole region. Three models were developed using Shell 63, Shell 181 and Shell 41. Shell 63 element supports both the membrane only and membrane-bending combined options and include stress stiffening and large deflection capabilities. Shell 181 include all these options as Shell 63 does and also, accounts for the follower loads. Shell 41 is a membrane element and does not include any bending stiffness. This element also include stress stiffening and large deflection capabilities. A nonlinear static analysis is performed for a simple plate model using the elements, Shell 41 and Shell 63. The membrane dominated behavior is observed for the shell model as the pressure load is increased. It is also observed that the higher value of Young's modulus (E) increases the stresses significantly. Transient analysis is a method of determining the structural response due to time dependent loading conditions. The full method has been used for performing the nonlinear transient analysis. Its more expensive in terms of computation involved but it takes into account all types of nonlinearities such as plasticity, large deflection and large strain etc. Implicit approach has been used where Newmark method along with the Newton-Raphson method has been used for the nonlinear analysis. Dynamic response comprising of displacement-time history and dynamic stresses has been obtained. From the displacement response, it is observed that the first movement of the back wall is out of the tent in contrast to the other sides whose first movement is into the tent. Dynamic stresses showed fluctuations in the region when the blast is acting on the structure and in the initial free vibration zone. A parametric study is performed to provide insight into the design criteria. It is observed that the mass could be an effective means of reducing the peak responses. As the value of the Young's Modulus (E) is increased, the peak displacements are reduced resulting from the increase in stiffness. The increased stiffness lead to reduced transmitted peak pressure and reduced value of maximum strain. But a disproportionate increase lead to higher stresses which could result in failure. Therefore, a high modulus value should be avoided. / Master of Science

Ce travail s'inscrit dans le cadre des recherches menées autour de l'analyse et la visualisation des logiciels, notamment les logiciels à objets, et en particulier Java. Très brièvement, on peut dire que le but de cette thèse revient à tenter de répondre à une question fondamentale: comment faire pour faciliter la compréhension du logiciel par ses développeurs et concepteurs ? Ce travail de recherche est basé en grande partie sur deux axes principaux. Le premier consiste à analyser l'exécution des programmes, non seulement au niveau de la méthode, mais bien au niveau du bloc de base, pour recueillir des données d'exécutions avec un maximum de précision comme par exemple les différents types d'instances sur les sites d'appels. Le second axe considère l'utilisation des informations apportées par notre analyse dynamique de l'exécution pour permettre la visualisation de ces données. En effet, ces informations offrent des détails intéressants sur le fonctionnement du programme et aident à expliquer le comportement du logiciel, aussi bien pour déceler les problèmes de performance que les problèmes de codages. Nous proposons une technique souple et efficace qui effectue une analyse dynamique de l'exécution de programmes Java. Nous introduisons ainsi une nouvelle technique et un nouvel outil permettant de recueillir des informations encore non proposées par d'autres analyseurs. Cette approche trace l'exécution précise des programmes tout en ayant une baisse des performances d'exécution acceptable, laissant le programme final utilisable. De plus, nous proposons et expérimentons une approche basé sur la visualisation des relations au sein d'une représentation du logiciel par une métaphore de ville. Nous introduisons une nouvelle technique de représentation des relations nommée "3D HierarchicalEdge Bundles" qui est basée sur une représentation 2D existante nommée "HierarchicalEdge Bundles". Cette approche conserve la puissance de visualisation du logiciel offerte par la métaphore de la ville tout en ajoutant la représentation des relations, et cela d'une façon lisible. Ces travaux sont validés entre autres par le développement d'un outil d'analyse nommé VITRAIL JBInsTrace et d'un outil de visualisation nommé VITRAIL Visualizer. Ces outils sont la base de nos recherche actuelles sur l'étude de l'exécution des programmes objets / This work falls within the scope of research pertaining to the analysis and the visualization of software systems, especially for object oriented languages, and more precisely Java. In a nutshell, it can be said the aim of this thesis is to try to answer a fundamental question: what can we do to ease the understanding of software by its designers and developers ? This research work is mainly based on two axes. The first axis consists in analyzing software runtime, not only at method level, but also at basic bloc level, so as to be able to get meaningful and precise information about the runtime. For instance, we can acquire the different types of instances on call sites at runtime. The second axis considers the use of information coming from our dynamic analyzer of software runtime and allowing the visualization of these data. Indeed, this kind of information offers important details about software functioning and provide a way to explain the behavior of software, so as to identify performance, coding and even design and architecture issues. We propose a technique that allows flexible and efficient dynamic analysis of the execution of Java programs. We thus introduce a new technique and tool for gathering information not yet offered by other analyzers. This approach precisely traces the execution of programs with acceptable performance penalty, that is while keeping the traced programs usable. In addition, we propose and experiment an approach based on visualizing relationships within a software city representation. We introduce a new technique for representing relationships in 3D named the "3D Hierarchical Edge Bundles" that is based on an existing 2D technique, the "Hierarchical Edge Bundles". This approach keeps the power of the software city metaphor while adding the representation of the relationships within the software, in a readable way. These works are validated by, among others things, the development of a tracer and analyzer tool called VITRAIL JBInsTrace and a visualization tool called VITRAIL Visualizer. These tools are used on our current researches which consist in studying runtime of object-oriented programs

The purpose of this study is to determine the most suitable remediation technique via geotechnical assessment of the landslide that occurred during the construction of Bursa-ineg&ouml / l-Boz&uuml / y&uuml / k Road at KM: 72+000-72+200 in an ancient landslide area. For this purpose, the geotechnical parameters of the mobilized soil along the slide surface was determined by back analyses of the landslide at four profiles by utilizing the Slope/W software. The landslide was then modeled using coupled analyses (with the Seep/W and Slope/W softwares) along the most representative profile of the study area by considering the landslide mechanism, the parameters determined from the geotechnical investigations, the size of the landslide and the location of the slip circle. In addition, since the study area is located in a second degree earthquake hazard region, pseudo-static stability analyses using the Slope/W software were performed incorporating the earthquake potential. The most suitable slope remediation technique was determined to be a combination of surface and subsurface drainage, application of rock buttress at the toe of the slide and unloading of the landslide material. A static and dynamic analyses of the landslide was also performed through utilizing finite element analyses. The static analyses were calibrated using the inclinometer readings in the field. After obtaining a good agreement with the inclinometer readings and finite element analyses results, the dynamic analyses were performed using acceleration time histories, which were determined considering the seismic characteristics of the study area.

This thesis examines the seismic internal retrofitting of existing deficient reinforced concrete (RC) structures by using structural steel members. Both experimental and numerical studies were performed. The strengthening methods utilized with the scope of this work are chevron braces, internal steel frames (ISFs), X-braces and column with shear plate. For this purpose, thirteen strengthened and two as built reference one bay one story portal frame specimens having 1/3 scales were tested under constant gravity load and increasing cyclic lateral displacement excursions. In addition, two &frac12 / scaled three bay-two story frame specimens strengthened with chevron brace and ISF were tested by employing continuous pseudo dynamic testing methods. The test results indicated that the cyclic performance of the Xbrace and column with shear plate assemblage technique were unsatisfactory. On the other hand, both chevron brace and ISF had acceptable cyclic performance and these two techniques were found to be candidate solutions for seismic retrofitting of deficient RC structures. The numerical simulations by conducting nonlinear static and dynamic analysis were used to estimate performance limits of the RC frame and steel members. Suggested strengthening approaches, chevron brace and ISF, were also employed to an existing five story case study RC building to demonstrate the performance efficiency. Finally, design approaches by using existing strengthening guidelines in Turkish Earthquake Code and ASCE/SEI 41 (2007) documents were suggested.

Actuellement, la restauration des oeuvres d’art, notamment des statues fracturées, repose sur des techniqueséprouvées, mais empiriques. Les statues endommagées comportent souvent des parties brisées. Leur restaurationconsiste la plupart du temps à les rassembler. Ainsi apparait la nécessité de prendre en compte lespropriétés mécaniques des interfaces entre les différentes parties brisées, ce qui permet de limiter l’ampleur desréparations et ainsi, de mieux conserver l’intégrité de l’oeuvre. Par ailleurs, les techniques numériques d’acquisition3D font leur entrée au service de la conservation du patrimoine. Cette thèse propose une méthodologiecapable d’utiliser des données issues d’une acquisition 3D pour simuler les opérations de restauration et leurseffets sur la structure de l’oeuvre. Les processus de restauration peuvent ainsi être testés et optimisés.Un scanner laser est utilisé pour l’acquisition de la géométrie des oeuvres, ce qui nous permet de reconstruireun modèle 3D pour la simulation numérique. Les calculs sont menés dans le cadre de la mécanique des milieuxcontinus déformables avec FLAC3D. Pour vérifier tous les points clés garantissant la stabilité mécanique, lecomportement des éléments de renforts et celui des interfaces entre les blocs ont été considérés. À partirdes résultats de ces études, une critique des stratégies de restauration mises en oeuvre ou envisageables estproposée.De plus, plusieurs méthodes de caractérisation visant à retrouver la provenance du matériau et/ou estimerles propriétés mécaniques de l’oeuvre sont proposées : caractérisations physico-chimiques et minéralogiques,essais non destructifs et destructifs. Une campagne expérimentale visant à caractériser le comportement desfractures en contact frottant avec acquisition de l’état de surface a été réalisée. Une analyse des corrélationsentre les propriétés mécaniques et morphologique des interfaces est ensuite élaborée. Enfin nous proposonsdes modèles prédictifs construits par régressions linéaires multiples et multivariées. Cette étude permet desimuler le comportement d’une oeuvre fracturée. / Currently, the artworks restoration, including broken statues, are based on proven but empirical techniques. Damaged statues often have broken parts. Restoration mainly consists in joining these parts. Thus appears the necessity of taking into account the interfaces mechanical properties between the different broken parts, reducing thereby the extent of repairs and thus better maintain the integrity of the work. Beside this, digital 3D acquisition techniques become more and more popular among the cultural heritage community. This thesis proposes a methodology able to use 3D acquisition datas to simulate the restoration operations and their effects on the structure. The restoration strategy can thus be tested and optimized. A laser scanner is used to acquire the statue geometry, allowing to reconstruct a 3D model for numerical simulation. Computations are carried out within the framework of deformable continuum mechanics using the FLAC3D software. In order to check all the key points ensuring mechanical stability, the behavior of reinforcing elements and those of the interfaces between blocks were considered. From the results of the present studies, a critical analysis of implemented or possible restoration strategy is proposed. In addition, several characterization methods to find the material origin and/or estimate the mechanical properties of the work are proposed : physico-chemical and mineralogical characterizations, non-destructive and destructive tests. An experimental campaign to characterize the behavior of fractures in contact with surface acquisition was performed. An analysis of correlations between mechanical and morphological interfaces properties is then developed. Finally, we propose a predictive modelling based on multiple linear and multivariate regressions. This study allow the simulation of fractured artworks behaviour.

Sabe-se que materiais compostos laminados são, hoje em dia, geralmente usados nas indústrias aeronáutica, aeroespacial, naval e outras, principalmente por causa de suas atrativas propriedades se comparadas aos materiais isotrópicos, como alta rigidez/peso, alta resistência, alto amortecimento e boas propriedades relacionadas ao isolamento térmico e acústico, entre outras. Porém, o comportamento de estruturas feitas de materiais compostos pode ser aperfeiçoado através da utilização de materiais inteligentes. Dentre os diferentes tipos comercialmente disponíveis de materiais inteligentes, os materiais piezelétricos são amplamente usados como sensores e atuadores para o monitoramento e controle de estruturas. O efeito piezelétrico direto define que uma deformação mecânica aplicada ao material é convertida em uma carga elétrica. Por outro lado, o efeito piezelétrico inverso define que um potencial elétrico aplicado ao material é convertido em deformação mecânica. Estes efeitos governam a interação eletromecânica nos materiais piezelétricos. O Método dos Elementos Finitos, uma ferramenta amplamente reconhecida e poderosa para a análise de estruturas complexas, é capaz de realizar a integração dos componentes inteligentes e das partes estruturais clássicas. Sendo assim, o comportamento estático e dinâmico, linear e geometricamente não-linear, de estruturas compostas laminadas delgadas com lâminas piezelétricas incorporadas é analisado neste trabalho usando o Método dos Elementos Finitos (MEF). Elementos triangulares, chamados GPL-T9, com três nós e seis graus de liberdade por nó (três componentes de deslocamento e três de rotação) e um grau de liberdade por camada piezelétrica (potencial elétrico) são usados. Para a análise estática não-linear as equações de equilíbrio são solucionadas usando o Método do Controle de Deslocamentos Generalizados (MCDG) enquanto a solução dinâmica é obtida usando o Método de Newmark com Formulação Lagrangeana Atualizada (FLA). O sistema de equações é resolvido usando o Método dos Gradientes Conjugados (MGC) e nos casos não-lineares um esquema iterativo-incremental é empregado. Diversos exemplos numéricos são apresentados e comparados com resultados obtidos por outros autores com diferentes tipos de elementos e diferentes formulações. A concordância entre estes resultados demonstra a validade e a eficácia dos modelos desenvolvidos. / It is well known that laminate composite materials are nowadays commonly used in the aeronautical, aerospace, naval and other industries mainly because their attractive properties as compared to isotropic materials, such as higher stiffness/weight, higher strength, higher damping and good properties related to thermal or acoustic isolation, among others.

Among several kinds of commercially available smart materials, the piezoelectric materials are widely used as sensors and actuators for the monitoring and control of structures. The direct piezoelectric effect states that a mechanical strain applied to the material is converted to an electric charge. On the other hand, the converse piezoelectric effect states that an electric potential applied to the material is converted to mechanical strain. These effects govern the electromechanical interaction in piezoelectric materials. The finite element method, a widely accepted and powerful tool for analyzing complex structures, is capable of dealing with the integration of smart components and classic structural parts.

Triangular elements, called GPL-T9, with three nodes and six degrees of freedom per node (three displacement and three rotation components) and one degree of freedom per piezoelectric layer (electrical potential) are used. For static analysis the nonlinear equilibrium equations are solved using the Generalized Displacement Control Method (GDCM) while the dynamic solution is performed using the classical Newmark Method with an Updated Lagrangean Formulation (ULF). The system of equations is solved using the Gradient Cojugate Method (GCM) and in nonlinear cases an iterative-incremental scheme is employed. Several numerical examples are presented and compared with results obtained by other authors with different kind of elements and different schemes. The agreement among these results demonstrates the validity and effectiveness of the developed models.

Worms have been improved and a range of sophisticated techniques have been integrated, which make the detection and response processes much harder and longer than in the past. Therefore, in this thesis, a STAKCERT (Starter Kit for Computer Emergency Response Team) model is built to detect worms attack in order to respond to worms more efficiently. The novelty and the strengths of the STAKCERT model lies in the method implemented which consists of STAKCERT KDD processes and the development of STAKCERT worm classification, STAKCERT relational model and STAKCERT worm apoptosis algorithm. The new concept introduced in this model which is named apoptosis, is borrowed from the human immunology system has been mapped in terms of a security perspective. Furthermore, the encouraging results achieved by this research are validated by applying the security metrics for assigning the weight and severity values to trigger the apoptosis. In order to optimise the performance result, the standard operating procedures (SOP) for worm incident response which involve static and dynamic analyses, the knowledge discovery techniques (KDD) in modeling the STAKCERT model and the data mining algorithms were used. This STAKCERT model has produced encouraging results and outperformed comparative existing work for worm detection. It produces an overall accuracy rate of 98.75% with 0.2% for false positive rate and 1.45% is false negative rate. Worm response has resulted in an accuracy rate of 98.08% which later can be used by other researchers as a comparison with their works in future.

This diploma thesis deals with the design of a new bridge construction over a multi-lane communication. The converted road is a pedestrian and biking trail connecting significant agglomerations. Three studies were worked out in this thesis and the C variant was selected for further detailed processing. It is an unsymmetrical suspended bridge with a cast-in-place deck. In the section above the communication, the bridge is made up of prefabricated segments. Suspension of the structure is made of two sloping pylons forming a V-shape. The analysis of the construction was carried out in the MIDAS Civil program, where a complete model of construction was entered, including a subsequent estacade. The model describes the construction process and includes creep and shrinkage of the concrete. The traffic, temperature and wind loads were used. The design was assessed for the ultimate limit states and serviceability limit states. The assessment was carried out in the IDEA StatiCa program, supplemented by manual calculations. The static calculations also include assessment of the harmonic response. Subsequently, overview drawings, detailed drawings and visualizations were developed.
