Obtenção de esforços em lajes maciças finas pelo método de elementos finitos

Abstract

The constant growth of technology, both of computer programs and as with processors, it is a reality all over the world. Mozambique, being a developing country, can take advantage by creating programs for computers and/or algorithms because their development is less expensive. In this work, it is researched how to take greater advantage of this growth technology for the study of thin slabs in civil engineering. The most recommended method for studying slabs is the finite element method. for providing values ​​very close to reality. Therefore, a search was literature in order to understand how materials behave, their elasticity and the general equations. After understanding the materials and their behavior, the slabs were studied in order to understand its workings in particular and obtain its governing equations. It was also studied in general, other methods used in slabs and understand the advantages and disadvantages of each. Based on the behavior and general equations of the slabs, an algorithm is developed that allows the calculation of different values ​​such as deflections, rotations, twists and moments. This algorithm is developed based on already developed subroutines because, this is a mathematical procedure and in most cases, certain calculations are already have developed subroutines. After the development of the algorithm, an analysis of the results is made. provides, comparing them with those of a simplified method and software in order to assessing its reliability.
