Utilização de modelos de cálculo para projeto de edifícios de paredes de concreto armado moldadas no local. / The use of design models for project of reinforced concrete wall buildings casted in place.

Braguim, Thales Couto 02 August 2013 (has links)
Desde meados de 2007, um aumento significativo de unidades construídas pelo sistema Paredes de concreto tem influenciado o mercado da construção habitacional no Brasil. Em abril de 2012, foi publicada uma norma brasileira que trata exclusivamente desse sistema. Além disso, o desafio em minimizar o déficit habitacional estimula a utilização desse método alternativo, pois quando aplicado adequadamente proporciona alta produtividade e menor custo em relação a outros métodos construtivos. Por essas razões, é importante conhecer quais modelos de cálculo são seguros e pertinentes para a análise estrutural de edificações construídas pelo sistema Paredes de Concreto. Neste trabalho são avaliados, por meio da comparação de resultados, quatro modelos de cálculo, dos quais dois são numéricos, utilizados para o pré-dimensionamento e dimensionamento de paredes de concreto armado, moldadas no local. Este tipo de estrutura tem sido bastante utilizada na construção de edifícios. Deste modo utilizou-se como estudo de caso, um projeto adaptado de um edifício real com quinze pavimentos tipo, para a aplicação dos modelos de cálculo e algumas normas de projeto. Os dois modelos numéricos foram desenvolvidos no software SAP2000, baseado no Método dos Elementos Finitos, considerando análise elástica linear. O primeiro discretiza as paredes com elementos de casca e o segundo com elementos de barra. A interação entre o solo e a estrutura não foi considerada neste trabalho. Normas de projeto foram comparadas na etapa de pré-dimensionamento quanto às resistências últimas à compressão com objetivo de avaliar a recente norma brasileira. A verificação ao dimensionamento das paredes quanto às tensões normais de compressão e tração e tensões de cisalhamento foi realizada baseada nas expressões da NBR 16055:2012. Por fim, verificou-se o Estado Limite de Serviço das deformações excessivas globais, referentes à movimentação lateral do edifício e a estabilidade global do edifício estudado, pela NBR 6118:2007. / Since 2007, a significant use of the system known as Concrete Wall has been influenced the Brazilian residential construction market. In April 2012, a Brazilian code exclusively devoted to this system was published. Besides that, the challenge in reducing housing deficit estimulate the use of this alternative method, because when properly applied it provides high productivity and lower costs compared with other construction methods. For these reasons it is important to evaluate which designing models are safe and appropriate to structural analysis of buildings constructed in Concrete Wall system. In this work it is evaluated, through results comparison, four designing models, of which two are numerical, used to pre-design and to design reinforced concrete walls casted in place. This kind of structure has been widely used in buildings construction. Thus, an adapted project from a real building with fifteen floors was used as a case study in order to apply the designing models and some project design codes. Both numerical models were developed in SAP2000 software, based on Finite Element Method, considering elastic linear analysis. The former used shell elements to represent the walls and the latter used frame elements. The soil-structure interaction has not been considered in this work. Project design codes were compared at the pre-design stage in terms of the ultimate compression resistance, aiming evaluate the recent Brazilian code. The check of normal stress of compression, normal stress of tension, and shear stress, was made based on NBR 16055:2012 expressions. Finally, the service limit state related to global excessive deformation due to the lateral movement of the building and the global stability was verified through NBR 6118:2007.

An Investigation On The Performance Of Aluminium Panel Curtain Wall System In Relation To The Facade Tests

Sengun Dogan, Banu Nur 01 January 2013 (has links) (PDF)
Extruded aluminium has become the material of choice for building envelope owing to its lightness, wide range of possibilities for profile design, durability and the eco-friendly attitude. In the light of recent technological developments in metal and glass industries, there has been various new approaches towards aluminum curtain wall systems which are mostly preferred by architects in high-rise buildings. Herein, the panel curtain wall system is determined as innovative and the modern aluminium curtain wall system. Furthermore, in the recent prestigious high-rise buildings, the demand of the architects and the contractors begins to replace the conventional curtain wall system which is constructed via stick construction technique, with panel curtain wall system which is applied to the building in a modular form . The main aim of this study is to investigate why the panel curtain wall system comes to the forefront especially for high-rise buildings. Accordingly, the basic architectural, structural and constructional design principles of unitized aluminium curtain wall systems are defined, analyzed and then the advantages and disadvantages of this system are pointed out from an architectural point of view. In order to evaluate the performance of panel curtain wall system against environmental factors, the facade tests, which are new and still-developing methods in Turkey, are used. The extensive facade tests have been conducted on full-scale specimen under field conditions reproduced in an equipped test chamber by authorized facade testing company and the assessment of this curtain wall performance was provided accordance with related standards. The two story full-size specimen, was 3000 mm to 7600 mm, belongs to one of the prestigious office towers constructed in Istanbul. The facade tests conducted to the specimen include watertightness, air permeability, wind resistance and building movement tests. In this study, the performance criteria of panel curtain wall system were investigated not only against environmental factors but also against human sourced factors. It is expected that this study will provide a guideline for system designers on the future research and development phase and for architects on the selection of curtain wall systems for their buildings due to the conducted test results and other advantages taken throughout this study.
