Prestressed hybrids of AAC and HPC : The BCE (Block Composed Element) building system. A conceptual studyBagheri, Hamid January 2006 (has links)
<p>There is an important potential for a development of a building system, if the present AACblock plants are completed with high performance concrete and pre-stressing technique. This can be done as a continuation of a present AAC production or in a site factory.</p><p>Hybrid cooperation between AAC and concrete is not a new technology. Traditionally, AAC is covered with rendering. The wetted material is first sprayed with cement slurry after which comes lime/cement-based rendering which strengthens the wall and supplies a mechanical protection. AAC blocks can be used as infill members in concrete deck plates and concrete framed walls (Hellers, 1993), in which the shrinkage of the surrounding concrete locks completely the cured blocks into a stable composite.</p><p>A good cooperation between AAC and concrete is a requirement for the pre-stressed hybrid. This combination has been investigated with reference to bond and moisture content. The interface must have sufficient bond to supply shear strength to the structural member. Also, the concrete should be suitable for pre-stressing which requires a minimum strength class K40. Here, K60 is applied in order to reduce creep and avoid creep failure of the AAC. A production layout for the purpose is suggested.</p><p>This research consists of three parts:</p><p>1- Hybrid concrete elements The principal formulation of hybrids, built on cooperation between two concrete materials, a weak AAC and a strong HPC poured on top, shows that this combination unites the most favourable qualities of the two concretes into a structural element with rational building technology.</p><p>Load-bearing capacity is good, and the fire protection is excellent. Through pre-stressing of the structural concrete, a crack-free behaviour is guaranteed up to the service limit, and deflection from dead weight (incl. floor covering and possibly half the service load) be eliminated. The most important structural elements needed in a building system could be taken as hybrids. In drawings, different members like floor- roof- and wall members, window and door lintels are shown.</p><p>2- Production system for hybrids AAC blocks form a bed containing the pre-stressing steel in slits and on which high performance concrete is poured. Pre-stressing brings the two concretes together. This is especially important for the shear capacity of a building member, by which extra dowels can be omitted. The pre-stressing force is anchored by plates directly against the cured AAC blocks. A special pre-stressing bed is not required. The production is arranged in such a way that necessary equipment (trays, form strips, wedges, locks) are circulated within twenty-four hours. The necessary manpower for this facility is analysed. Normally 8 men are needed per shift.</p><p>A detailed conceptual production layout for a hybrid production plant is included for discussion. See figure 6.2 (suggested production layout).</p><p>3- Application in building The hybrid members are united at joints and through seams. Continuity over connections is achieved by filling seams with mortar grout. Reinforcement may be included to achieve ductility. By a similar method, it is possible to make connections between horizontal and vertical building members. Common connection details are shown in the report. This building method replaces the equivalent method with concrete or AAC members, and it is in fact a coordination between these two.</p><p>The maximum span of floor members is up to 9 m. It makes the system suitable for modern residential house production, but also suitable for office buildings, industrial halls and other applications. See attached drawings, part 2 and part 3.</p>

A critical analysis of the continued use of Georgian buildings : a case study of Darley Abbey Mills, DerbyshireDeakin, Emmie Lousie January 2016 (has links)
This thesis undertakes a critical assessment of the impact of Statutory Legislation and UNESCO World Heritage Designation upon the sustainability and continued use of historic industrial buildings, utilising the late 18th Century Georgian Industrial Buildings of Darley Abbey Mills, Derby, as a case study. This thesis provides an indepth and longitudinal analysis of the morphology and evolution of Darley Abbey Mills between 2006-2015, during this time the assessment of whether the mills would find a sustainable and continued contemporary use has shifted from a concern that the site was slowly disintegrating with the danger of an important historical artefact being lost for ever or becoming irrevocably damaged through lack of maintenance and repair to a position where the future of the mills is looking promising. What makes Darley Abbey Mills so unusual or unique is that it possesses the highest possible levels of statutory protection, but that is also under private ownership. The initial findings in an analysis of policy documents and planning applications between 2006- 2010 was that there was limited engagement with the external heritage and conservations stakeholders or the Local Authority, an ‘umbrella of statutory protection’ was not providing barriers or protecting the site, there was just a lack of action by all parties. This changed during the period 2010-13 when the site came under new unified ownership, the new owners started to make small adaptations and repairs to the site that enabled them to encourage new tenants from the creative and artisan communities to the site, however all of this work was not authorised, nor was planning permission sought. Although there was still a lack of enforcement of what can be seen as ‘aspirational urbanism’, a dialogue was started between the owners and the wider stakeholder community. Between 2013-2015, the relationship between all of the stakeholders became more formalised and an unofficial partnership was formed between the owners and the monitoring bodies that resulted in the successful planning application to adapt the West Mills and Long Mill, which moved some of the way towards ensuring the sustainable and continued use of Darley Abbey Mills.

Modern movement conservation : international principles and national policies in Great Britain and the United States of AmericaEngel Purcell, Caroline Marie January 2017 (has links)
This thesis analyses the roles played by international, national, regional and local organisations and discourses in the heritage valorisation and conservation of modernist architecture – a process that has so far spanned some three decades. A leading role in this narrative has been played by international conservation organisations, which have acted as a unifying front for conservation advocacy and defined a conservation ideology that integrates the principles of both the modern movement and the conservation movement. Partly, this international emphasis has stemmed from the characteristics of the 20th century Modern Movement itself, including its strong strain of cosmopolitanism, as well as its still controversial reputation today at a local level. This initially gave the proselytising of modernist conservation a somewhat elite, trans-national character, exemplified by pioneering organisations such as DOCOMOMO. Yet the ‘internationalism’ of modernist conservation is only part of the story – for to establish this innovative new strand of heritage on a more entrenched basis, the familiar, more locally specific organisations and discourses that had supported previous phases of conservation growth were also increasingly applied to ‘MoMo’ heritage. This ‘on the ground’ involvement represented a convergence with more ‘traditional’ conservation practices, both in advocacy and campaigning, and in the research-led documentation required to document buildings’ significance and continued fitness for purpose. These geographically-specific forces operate at both a national level and also a regional or even local scale, as the thesis illustrates by the two national case studies of Great Britain and the United States of America. Although both countries shared numerous cultural similarities, especially the 19th century veneration of private property, the far more emphatic 20th century turn towards state interventionism in Britain led to a strong divergence regarding modernist heritage, both in the overall character of the modernist architecture built in the two countries (far more ‘capitalistic’ in the US) and in the approach to heritage conservation (more state-dominated in GB). In Great Britain, following on from the comprehensive post-WWII government ‘listing’ programme, the statutory heritage bodies – ‘regionally’ differentiated between England and Scotland - have maintained their leading role in the conservation of modern movement heritage through initiatives to identify buildings of significance, and powerful city planning authorities have provided co-ordinated enforcement. In the US, on the other hand, heritage protection has stayed faithful to its philanthropic roots and the onus of modern movement conservation is left to voluntary advocacy groups who then must campaign to have buildings protected piecemeal by local city or state preservation bodies.

Pattern approach to architectural conservation : a temple town in IndiaVenkatraman, Namrata, 1981- 05 December 2013 (has links)
“Can the understanding of the patterns of urban development around a temple complex in India,
using Christopher Alexander’s methodology, help better preserve these temple communities and
their related temple architecture?”
India, a country largely governed by a spiritual culture, draws sustenance and strength largely
from religious buildings, thus leading to an emergence of many towns around these religious
buildings and events associated with them. The temple acts as the nucleus and the body of life
and township shoots from it with the cultural, religious and commercial needs acting as its driving
force. Certain groups of people having similar experiential, ideological and sociological
backgrounds tend to form a chorus in their pattern generation. The patterns refer to the patterns of
relationship between the events that occur in the temple with the various spaces that they occur
in. It also refers to the recurring relationships and influences of the temple on the temple town
including both the urban development and community which shoot around the temple. The
reverse recurring events also forms its own set of patterns. These patterns are seen both in the
physical development of streets, shops etc around and in the intangible aspects of the culture,
festivals and beliefs of people living in that town. Thus pattern language in this thesis refers to the
life, culture and architecture generated by the recurring interactions and interdependencies of the
temple communities as a whole.
Thus this thesis concludes that the thorough understanding of these interdependencies and
interconnections between the structure, its town and community helps preserve the temple
architecture as well the town and its intangible culture more effectively. This approach to
preservation makes the outcome more holistic and sustainable.
This thesis, through its case studies of an existing successful temple town in Puri, India and an
ongoing project of the Bindusagar lake, understands this interdependency and develops patterns to be applied in the context of a deteriorated temple village of Kapileswar. They are studied both
as sacred places and urban growths where communities thrive.
This thesis will focus its final chapters on the application of the studied patterns and its outcome
in the form of a preservation model for the Kapileswar temple and temple village based in Orissa,
India. However the model in its fundamental framework attempts to suggest that it can be applied
on any other setting, location and architecture. This proposed model summarizes the above
findings and tries to draw concepts for the preservation process of the Kapileswar temple village
based on a pattern approach. The above case studies and their comparative analysis very clearly
indicate the various similarities and dissimilarities between their respective settings and
approaches. The proposed model for the holistic preservation model of the Kapileswar temple
village draws its similarities from the culture, rituals, festivals, commercial endeavors, networks
and location of the Puri Jagannatha Temple and the Bindusagar project and its differences from
their management structure, devotee following, history, legends and economics. The model
includes the proposed management structure and execution structure of the preservation process
of the Kapileswar temple based on the above study that will help in the sustainable growth and
maintenance of the temple village as a whole. The nucleus of this model is the temple. The model
identifies the various elements that when incorporated in the co-operative society management
structure and the space allocation diagram form the necessary patterns that ultimately make up for
the pattern approach to preservation. The model also includes various charts and diagrams that
prioritize and compartmentalize the many small and big items, events and spaces as a part of the
above patterns. Hence the proposed model creates a flow of steps that will help preserve the
Kapileswar temple and village based on a holistic pattern approach. / text

Energieffektivisering i Karlstad stiftSöderström, Mikael, Broström, Tor January 2010 (has links)
Karlstad stift har under 2007 och 2008 genomfört vad man kallar ”Klimatprojektet”. Projektet består av tre delar; energiplanering, underhållsplanering och utbildning.Syftet är att stötta stiftets samfälligheter genom att dels genomföra energikartläggningarav sammanlagt 516 byggnader och dels underhållsplanera drygt 900 byggnader. Alla anställda inom samfälligheterna har dessutom genomgått en grundläggandeutbildning i energi- och miljöfrågor. Byggnaderna inom Karlstad stift använder idag ca 32 000 MWh energi fördelat påolika energislag där elanvändningen är dominerande med ca 18 000 MWh. Energikartläggningarnavisar att det sammantaget finns en besparingspotential på ca 30 %av energianvändningen med ca 40 % sänkta kostnader som följd genom effektiviseringav energianvändningen och byte av värmekällor. Underhållsplaneringen har genomförts enligt REPABs modell och samtliga byggnaderhar underhållsplanerats i programmet Summarum. Både energi- och underhållsplaneringenhar framför allt givit bra förutsättningar för att underlätta budgetarbetetinom samfälligheterna. Under projekttiden har dessutom en bra dialog mellan stift, samfälligheter, konsulter,antikvarier och entreprenörer startat. Man har börjat få en bättre förståelse förvarandras synsätt, framför allt hur man ser på antikvariska aspekter. Karlstad stift fortsätter nu med att stötta samfälligheterna till exempel genomdriftutbildning för vaktmästare och genom gemensamma upphandlingar av olikaåtgärder och el och man skall dessutom försöka dela med sig av erfarenheter ochmetoder för att sprida kunskaperna om energieffektivisering och underhållsplaneringtill andra stift i landet. Denna rapport har författats av Mikael Söderström Rosén på KanEnergi Sweden ABmed stöd av Tor Broström vid Högskolan på Gotland som också är beställare avrapporten. Arbetet har genomförts med ekonomiskt stöd från Energimyndighetensforskningsprogram ”Spara och bevara – energieffektivisering i kulturhistoriskt värdefullabyggnader”.

The conservation of archaeological sites in Syria : Ugarit as a case studyTeba, Tarek January 2017 (has links)
The conservation of cultural heritage responds to the necessities of understanding the site’s history, developments and key values. Archaeological heritage comprises tangible and intangible evidence so conservation operates equally on the two main domains, archaeology and architecture, which are inseparable and feed each other. Moreover, urban dimension is essentially included where the cultural heritage presents interesting urban settings linked to the architectural and cultural values. This thesis addresses all these important issues with the aim to identify, preserve and present the cultural values of archaeological sites in Syria, which are exceptionally rich in representing most of the Western ancient civilisations. The thesis focuses on the City of Ugarit, the capital of an important Bronze Age civilisation. The thesis aims to establish a poignant conservation concept on different scales, ranging from micro single architectural unit, the house, to the macro scale of the entire city. The study probes the ways of employing archaeology and architecture to produce conservation principles and architectural approaches for identifying, preserving and presenting the site’s cultural values. These procedures expose tangible and intangible values of the city, facilitate strong engagement of the visitors with the archaeological ruins, and simultaneously protect the original fabric from the visitation flux. The study is built upon understanding Ugarit’s archaeology, architecture and even social aspects, combining them in the analysis of each key area (Royal quarters, Domestic areas and Temples) to form well-founded interpretations and prioritise values. The proposal eventually combines all studied areas in a comprehensive narrative, which feeds the urban proposal for the whole city. In understanding the very rich and complex sites in Ugarit, a combination of in situ surveys, systematic recording, extensive analysis of literature and archaeological reports, and architectural reading of the fabric are carried out. This framework is a coherent base for the architectural intervention choices, which attempt to balance preservation implications and new materiality. Building virtual models of the proposed interventions enables the test of volumes, materiality, choices and the overall architectural experience. These models present the proposed interventions together with the original ruins. Therefore, the models are a great vehicle to transmit the reality of the conservation proposal and enhance its perception.
