摘要
半刚性节点具有较好的抗震性能,能很好地解决刚性连接节点延性不好、容易发生脆性破坏的问题。本文利用大型有限元软件ANSYS分析了外伸端板连接、平齐端板连接与刚性连接节点抗震性能的不同,并与单调荷载下静力性能相对比,研究了节点承载力、应力变形特性、延性及耗能性能,通过结果分析,指出了合理的外伸端板半刚性连接可以用于抗震设计中。
Semirigid joints have good seismic behavior,which can be a good solution to the bad ductility and prone to brittle failure problems of rigid connection joints. Differences of seismic behaviors of beam-column Joints with extended end-plat e connection,flush end-plate connection,and rigid connection have been analyz ed with the finite-elements software ANSYS in this paper;bearing capacity,str ess-strain characteristics,ductility and power-wasting capacity of joints are also studied comparing with static characters under monotonic loads.The result s show that a reasonable extended end-plate connection can be used in seismic d esign of steel frame structures.
