Abstract in Portuguese
O objetivo principal deste trabalho é sistematizar e automatizar o cálculo de lajes maciças e retangulares de edifícios, utilizando-se a Teoria das Charneiras Plásticas. Apresentam-se as formulações necessárias para a sua automatização. Aborda-se também a questão relativa às deformações nas lajes maciças em concreto necessidade de consideração das dependentes do tempo. Por fim, faz-se um estudo comparativo com o método elástico para dimensionamento de lajes maciças em concreto e com o sistema de lajes treliçadas, através de aplicações em dois pavimentos de lajes, analisando-se os aspectos técnicos e financeiros (custos) dos resultados.

Abstract in English
The main purpose of this work is to systematize the building rectangular compact slab calculation, using the yield line theory. The necessary formulation is presented. Deflections of reinforced concrete slabs are also discussed, making evident that cracking and time dependent effects are important parameters to be considered. Finally, a comparison with the elastic method for compact slabs design and with the lattice slab systems is presented, considering two examples of building floors, taking into account technical and financial (expenses) aspects of the results.
