摘要
利用数值积分法 ,并考虑损伤累积对钢材性能的影响 ,模拟了钢结构柱在任意空间交变受力下的非线性滞回过程 ,以代替试验手段进行钢结构柱空间恢复力特性的研究 .最后 ,通过计算机对 2根H形钢柱的空间恢复力特性的模拟仿真 。
In this paper, the whole process of nonlinear hysteretic behavior of steel columns under arbitrary spatial repeated loads is simulated in computer with numerical integral method. This computer simulation can be taken as an alternative of the experiment research of spatial hysteretic characteristics of steel columns, with consideration of the effects of steel damage on its characteristics during the whole integral process. Finally, the accuracy of proposed method was verified through the computer simulation of two H-sectioned steel columns of spatial hysteretic characteristics.
