摘要
通过钢框架顶底角钢带双腹板顶底角钢半刚性连接类型共五个原型试件在循环荷载作用下的拟静力试验 ,得到了各个试件M -θr 滞回曲线及骨架曲线 ,从而间接得到了各类连接的抗震性能 ,分析了各类连接的能量耗散机制 .在试验中 ,还记录了梁柱连接中重点部位的应变情况、节点域的变形情况以及柱节点域加劲板的变形情况 .分析了每种类型的破坏机制及破坏原因 .
The relations of all kinds of M θ r curve, skeleton curve and seismic behaviors were gained. All kinds of characteristic of dissipation of energy through pseudo static testing of five full scale connections under cyclic loading of top seat angle connections, top seat angle with two web on steel frame were analyzed. Strain situation of emphasis section in beam to column connections and transfiguration situation in knot position were recorded in the experimnet and failure characteristic and reason analyzed.
