Q460C高强度钢柱滞回性能有限元分析
Finite element analysis on hysteretic behavior of Q460c high strength steel box-section and H-section columns
摘要
Abstract
In order to further study the hysteretic behavior of Q460C high strength steel columns, a finite element ( FE) model was built up by using general FE analysis software ANSYS based on previous experimental study. Both welded box and H-section columns under constant axial load and horizontal cyclic loading were simulated. Moreover, the effect of residual stresses on the hysteretic behavior of Q460C steel welded box and H-section columns was evaluated. The FE analysis result shows good agreement with the existing experimental results conducted by authors. The proposed hysteretic model for Q460C high strength steel is proved to be accurate to be implemented in the numerical analysis. The comparison of FE analysis results with and without considering initial residual stresses shows that the influence of residual stresses on hysteretic behavior of Q460C high strength steel columns is negligible.关键词
