摘要
利用大型通用有限元分析软件ANSYS分析了十字形钢异形截面压弯构件受常轴力、循环弯矩作用下的滞回性能、强度、变形、延性及破坏特征,得到其滞回性能的主要影响因素及影响规律,可为抗震设防区采用十字形钢异形柱设计提供依据。
Using the finite element analysis software ANSYS, it was researched that the hysteretic behaviour, strength, deformation, ductility and damage features of the cross-section special-shaped steel columns forced by regular axial compression and cycle moment. And found the main factors effecting the hysteretic behaviour and the influence laws. Which provided a basis for the design and use of the cross-section special-shaped steel columns in strong earthquake defensive zones.
