【摘要】 为了探讨不同梁柱节点钢框架抗震性能的差别,通过ANSYS分析软件,对结合工程实际设计的10个系列共50个有限元试件进行时间历程分析,来探讨框架层数、框架跨数,尤其是梁柱连接节点的转动刚度等参数对钢框架抗震性能的影响.分析表明:半刚性钢框架结构在地震荷载作用下具有良好的抗震性能.更多还原

【Abstract】 In order to research of the seismic performance of semi-rigid steel frames,the paper design 10 series(altogether 50) of finite element analytic models.Furthermore,the time-history analysis is discussed in this paper to investigate the relations between frame parameters of semi-rigid steel frames,these parameters include the frame’s floor number,the frame’s span number and the frame’s damp,especially the rotation stiffness of beam-to-column connections.Comparing with the steel frame structure,semi-rigid steel frame structure under seismic loading has a good seismic performance.更多还原
