Abstract

Abstract

The stand seam roof is prone to failure under wind pressure. There is a lack of mechanical models and finite element analysis software that can numerically simulate the wind-induced response of stand seam roof systems. Firstly, the elastoplastic equivalent spring model for the stand seam roof was proposed according to the nonlinear wind-induced response of the structure, and the finite element algorithm for the elastoplastic equivalent spring element was derived, then the algorithm was embedded in the LiToSim platform to develop customized software LiToSpr for the stand seam roof. Finally, the structural responses were modeled, analyzed and compared with the anti-wind unmasking experiment results, to verify the applicability of customized software LiToSpr. The research indicates that, software LiToSpr can well simulate the wind-induced responses of the stand seam roof, and provides a reference for engineering design.
