摘　　要：采用SAP2000软件对摩擦耗能交错桁架结构体系进行静力弹塑性分析。首先进行普通交错桁架结构的设计,然后在普通交错桁架结构的适当位置设置摩擦耗能器形成摩擦耗能交错桁架结构体系。建立各结构的平面协同分析模型后,对各个模型进行静力弹塑性分析。分析结果表明,摩擦耗能器的设置可以避免或延缓结构的破环,增强结构的延性和耗能能力;因此摩擦耗能交错桁架结构体系的抗震性能远远优于普通交错桁架结构体系。Nonlinear static analysis for staggered truss framing system with friction dampers by using SAP2000 was carried out. Staggered truss framing system without friction dampers was designed first, then friction dampers were installed in proper places to form staggered truss framing system with friction dampers. After plane cooperating models for all structures were created, nonlinear static analysis for all models was carried out. The analysis results show that： Structural damage is avoided or suspended through installing the friction dampers and the ductihty and energy dissipation of structure is improved. The seismic performance of the staggered truss framing system with friction is far superior to that of the staggered truss framing system without friction.
