摘要
无比钢结构体系是一种新型的钢结构体系,该结构体系主要由小型桁架等基本单元组成,构造复杂。其墙体由于构件繁多,在有限元分析时十分不便。在借鉴等代拉杆简化模型的基础上,用SAP2000中的Pivot连接单元代替拉杆,进行墙体的简化分析,用一个无比钢结构实例进行对比,表明该简化方法在无比刚结构体系的弹性和弹塑性地震反应分析中的可行性。
Web-Steel structure system is a new type of steel structure system, which is mainly made of small trusses and has complex constitution. Due to the various components, the finite element analysis of the wall is very inconvenient. On the basis of the equivalent rod simplified model, asimplified analysis was studied by using the Pivot element in SAP2000 instead of rod. Compared with a case of Web-Steel building, the results show that the simplified analysis method can be used to elastic and elastic-plastic seismic response analysis of Web-Steel structure system.
