T形圆管相贯节点的低周往复受力性能研究

RESEARCH ON MECHANICAL PERFORMANCE OF T-JOINT OF CIRCULAR TUBE UNDER LOW REVERSED CYCLIC LOADING

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。

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.
