摘　　要：前期研究发现,折线形钢梁承受荷载作用时,其折点部位形成复杂受力状态,使钢梁结构体系受力性能发生较大变化。利用ANSYS有限元分析软件,采用平面杆系分析方法和三维立体有限元分析方法,对两端固定铰支座折线形钢梁进行力学分析。根据两种分析得出的不同力学数据,提出了折线形钢梁折点引起的结构体系力学综合效应影响。Previous studies found that when mansard steel beam beared loads, the turning point formed a complex stress state, which made the mechanical properties of the beam change greatly. Mechanical analysis was developed on both ends fixed hinge support mansard steel beam, using the method of plane link system analysis and three-dimensional finite element analysis, which both used ANSYS finite element analysis software. By analyzing the different mechanical data derived from the two methods, this paper proposed a theory of integrated effects of the mansard steel beam mechanical structure system caused by break point.
