摘要:为了比较PEC柱-钢梁端板连接和顶底角钢连接框架的滞回性能,设计了一榀端板连接框架和一榀顶底角钢连接框架,在低周反复水平荷载作用下进行试验。试验分析了端板连接节点和顶底角钢连接节点框架的极限承载力、破坏模式、滞回性能和延性。试验结果表明: PEC柱-钢梁端板连接框架和顶底角钢连接框架均具有良好的抗震性能,端板连接框架的的承载力比顶底角钢连接框架的承载力提高了6.84%,初始刚度提高了51.59%,延性提高了27.85%。

Abstract:In order to compare thehysteretic behavior of the PEC column-steel beam frame with end plateconnections and top-seat angle connections, two frames were designed and testedunder low frequency cyclic loading .Based on the experimental study, the bearingcapacity, failure mode, hysteretic curves and ductility were obtained. Theresults show that PEC column-steel beam frame with end plate connections andtop-seat angle connections have good seismic performance. The bearing capacityof the frame with end plate connections is higher than that of the top-seatangle connection frame, being increased by about 6.84%. The initial stiffnessand the ductility was increased by 51.59% and 27.85%, respectively.
