CÁLCULO DE PROPRIEDADES GEOMÉTRICAS DE SEÇÕES DE PAREDES FINAS ABERTAS, FECHADAS E MISTAS

Abstract

In the present work a computational technique was developed for the direct calculation of rectangular and sectoral geometric properties of open, closed and mixed thin-walled crosssection beams from a reference system placed at any point in the plane of the cross-section.. The program developed was coded in Mathcad, mathematics and engineering software, producing an evaluation of a set of straight and/or circular walls. The cross section is shaped by nodes and straight and / or curved segments, and the thickness must be constant in each segment. Some numerical examples are done and compared with the results found in the literature. In order to verify the proposed calculation for curved walls, an example shows the convergence of results when curved wall is discretized into several straight segmentos.
