摘要
进行了比例尺为 1∶2的两榀半刚性连接和一榀狗骨式刚性连接平面钢框架结构的拟静力试验 .通过试验考察了半刚性连接平面钢框架结构在循环荷载作用下的弹塑性性能 ,了解了结构在丧失极限承载力后的破坏形态和塑性铰出现的顺序 ,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 。
Pseudo-static force testing of models with 1:2 scale including two steel frames with semi-rigid connections and a steel frame with dog-bone rigid connections was carried out to obtain elastic-plastic behavior of semi-rigid connections steel frames under cyclic loading, and to analyze collapse characteristics after knowing the loss of the structural ultimate strength and the coming order of plastic hinges. This paper showed the relations of all kinds of M-θ_r curve, skeleton curve and seismic behaviors. All kinds of characteristics of hysteretic behavior were analyzed.
