摘要：
This paper aims to describe the development of a numerical model to accurately simulate the non linear buckling of self-weighted metallic roofs by the finite element method (FEM), which have different span lengths, ranging from 22 to 30 meters, and the same cross section. In this way, the collapse buckling load was calculated in two steps: firstly a linear buckling was carried out and secondly, an initial imperfection was added to the geometrical model and the non-linear analysis was performed. Finally the results and conclusions reached in this work are shown.
