摘    要:为了研究焊接H型钢部分包裹混凝土柱-型钢梁端板连接框架骨架曲线、延性、耗能能力等抗震性能,设计3榀框架试件在低周往复荷载作用下进行试验。试件参数是端板厚度和柱翼缘厚度。通过试验,研究讨论了改变端板厚度和柱翼缘厚度对框架抗震性能的影响:分析了试件的骨架曲线、延性、耗能能力抗震性能指标。试验结果表明:柱翼缘厚度从12 mm增加到16 mm,框架节点初始刚度增加39.95%,端板厚度从12 mm增加到20 mm,初始刚度增幅11.76%;增加端板厚和柱翼缘厚可提高框架初始刚度;3榀框架试件的延性系数在4.41~5.38之间,说明PEC柱与型钢梁端板连接框架具有良好的抗震性能;增加端板厚度和柱翼缘厚度可以增加框架结构塑性性能。

关 键 词:PEC柱  端板连接  骨架曲线  延性  耗能能力

Abstract:In order to study the seismic performance of the frame structure, the frame curve, ductility and energy dissipation capacity of the welded H steel partially encased concrete column and steel beam end plate,The design of 3 frame test specimens under cyclic load. The parameters are the end plate thickness and the flange thickness. Through the test, the influence of the thickness of the end plate and the thickness of the flange on the seismic performance of the frame is discussed, The framework curves, ductility and energy dissipation capacity of the specimens are analyzed.Experimental results show that the thickness of the flange is increased from 12mm to 16mm, and the initial stiffness of the frame is increased by 39.95%; The thickness of the end plate increased from 12mm to 20mm, and the initial stiffness increased by 11.76%;Increasing the thickness of the end plate and column flange can improve the initial stiffness of the frame; 3 frames try ductility coefficient between 4.41- 5.38, PEC columns and steel beam end plate is connected with the frame has good anti-seismic performance; Increasing the thickness of the end plate and the column flange can increase the plastic properties of the frame structures.
Keywords:PEC column  End plate connection  Skeleton curve  ductility  Energy dissipation capacity
