Title in Portuguese
Cálculo de esforços e deslocamentos em pavimentos de edifícios considerando-se modelos próprios para o concreto armado
Keywords in Portuguese
Concreto armado
Elementos finitos
Estruturas reticuladas
Não-linearidade física
Abstract in Portuguese
O objetivo deste trabalho é fornecer uma contribuição à análise estrutural de pavimentos de edifícios de concreto armado. Com esse fim, foram implementados os modelos de DEBERNARDI e de GHALI & FAVRE, próprios para barras de concreto armado. Os resultados são obtidos para o instante de aplicação de um carregamento e para um instante qualquer de tempo, considerando-se a fluência. Apresenta-se, no decorrer do trabalho, o equacionamento dos modelos e das variáveis envolvidas no processo. São mostrados exemplos práticos de aplicação dos algoritmos desenvolvidos e discute-se, nos capítulos finais, a redistribuição de momentos que ocorre em estruturas reticulares de concreto armado.

Abstract in English
The aim of this work is to give a contribution to structural analysis of reinforced concrete building floors. Therefore, DEBERNARDI's and GHALI & FAVRE's models for reinforced concrete were implemented. The results are obtained at the loading application instant and at any instant of time, considering therefore the creep. In this work, it is presented the formulations of the adopted models and the variables used in the process. Some practical examples of application for the developed algorithms are shown. Finally, it is discussed the redistribution of bending moments that may occur in reinforced concrete grid structures.
