摘要:
对钢结构交错桁架体系在强震作用下的工作性能进行了研究。通过采用改进的静力弹塑性(NSP)分析方法,在对一个交错桁架体系实例的原结构方案进行修改的基础上,分析了交错桁架结构布置方案在强震作用下的破坏模式和延性要求的一般特性,得到了不同布置方案在强震作用下的破坏模式特点和各个楼层的延性要求。分析结果表明:在强震作用下交错桁架体系的塑性铰发展多集中在桁架腹杆中,柱中一般无塑性铰出现,结构刚度退化小,变形能力强,具有良好的抗震性能和延性能力。
Abstract:
The works on the performance behavior of staggered truss system of steel structure under severe earthquake were studied. Through using the modified nonlinear static procedure(NSP)method, an engineering example using staggered truss system and a modified proposal based on the original design scheme were fully investigated. The failure mode and ductility requirement of the two proposals under severe earthquake were presented in detail, and the characteristics of failure mode and ductility requirement of interfloor displacement of the two proposals under severe earthquake were also gained. The analysis results indicate that plastic hinges mostly concentrate on truss web member, and there is no plastic hinge in column, that the deformability of staggered truss system which has good earthquake resistance capability and ductility under severe earthquake is good and stiffness degradation is obscure.
