Stability Analysis of Roof Structure with Steel Tubular Arch-Truss

Abstract:

Based on the stability theory, one roof structure with steel tubular arch-truss was taken as a research object. Linear buckling, geometric nonlinear stability and elastic-plastic nonlinear stability were investigated by applying ANSYS finite element software, and the relational curves of critical load-displacement were obtained. The analysis results show that material nonlinear makes obvious influence on the stability of the structure, material nonlinear and geometric nonlinear are taken into account at the same time can make a better understanding of the structural stability performance.
