摘　　要：对6个分别为现浇、分散预埋槽钢、集中预埋槽钢的L形柱框架节点进行低周反复荷载试验,得到几种制作形式不同的L形柱框架节点的破坏形态。对比分析现浇和预制的L形柱框架节点的滞回特性、耗能、承载力和延性。试验结果表明:预制L形柱框架节点与现浇L形柱框架节点的破坏形态基本相同,并均属于"强柱弱梁"型破坏;预制L形柱框架节点和现浇L形柱框架节点的抗震性能也基本相同,能够满足抗震规范的要求和工程的需要。Low-cyclical loding experiments of six L-shaped column frame joints with the types of pouring,scattered embedded channel steel and centralized embedded channel steel were carried out.Several failure modes of L-shaped column frame joints with different fabrication types were obtained. The hysteretic behavior,energy dissipation capacity,bearing capacity and ductility of L-shaped column frame joints between casting and prefabricated were analyzed and compared.The experiment results indicated that the prefabricated L-shaped column frame joints had similar failure modes with the casting frame joints and both of them were the beam hinge failure.Both the prefabricated and casting L-shaped column frame joints had similar seismic performance,could meet the requirements of seismic code and real application.
