Análise dinâmica de pórticos planos pelo Método dos Elementos Finitos

Abstract

The dynamic analysis of 2D frames is a relevant topic for structural engineers, since the civil construction advances, in a quick way, technologically as the time passes. This allows the creation of increasingly taller structures which are highly stressed due to dynamic loads, such as the wind. Thus, this work aims at the development of a computational code using the software MATLAB. The code solves 2D portals problems through the Finite Elements Method (FEM), using frame elements, obtaining the internal efforts of the structure, and in addition it analyzes certain displacements, at the user's discretion, through two methods consolidated in the study of structural dynamics, the methods of Newmark and Houbolt, the study also deals with the use of constant and variable dynamic loads.
