摘　　要：对八个带双腹板顶底角钢连接以及外伸端板连接空间钢框架进行了非线性有限元分析,并与刚性连接空间钢框架进行了分析对比,从而探讨了空间钢框架的静力承载性能与节点刚度的关系,得到了不同节点刚度对空间钢框架位移和内力的影响结果以及随楼层变化半刚性连接对钢框架性能的影响。研究结果为半刚性连接空间钢框架在工程中的应用提供了一定的理论依据。Nonlinear finite element analysis is performed in this paper for eight space steel frames with top-seat-angle and double web-angle connections and extended endplate, and comparative analysis of space rigid steel frame is also presented. The relationship between joint stiffness and static behaviors on space steel frames is simply studied, to find out the influence of joint stiffness and change of numbers of frame stories on the deformations and internal forces of the space steel frames. This research results can be taken as a reference for engineering application of space steel frame with semi-rigid connections
