摘要: 通过对T形相贯节点在低周往复荷载作用下的试验,研究该节点的破坏形式、受力性能,同时对该节点进行有限元模拟分析,其结果与试验结果较为吻合。分析结果表明:T形圆管相贯节点具有较好的延性。T形相贯节点的滞回曲线稳定饱满,具有较为理想的抗震耗能作用。

Abstract: Through experiment on the T-joint of circular tube under low reversed cycilc loading,the damage form and mechanical performance of T-joint of circular tube has been studied.At the same time,a finite element analysis by ANSYS software was done,whose results are in good agreement with those of the tests.The analytic results show that T-joint has better ductility;the shape of P- curve is stable and full,T-joint has perfect seismic performance.
