| 摘 要： | 为研究焊接环式箍筋柱与焊接蜂窝梁连接节点的破坏特征和抗震性能,进行了2个外伸式端板连接节点、2个平齐式端板连接节点的低周反复荷载试验,分析了各节点的破坏形态、承载力、延性、耗能性能、刚度退化等。试验结果表明:外伸式端板螺栓连接型试件的承载力最高,延性最好,耗能能力较强,但在极限荷载之后出现严重的刚度退化。

| Abstract: | A series of specimens,including 2 extended end-plate connection joints、2 end-plate connection joints under low-cycle cyclic load were tested in order to research the failure characteristic and anti-seismic performance.The failure modes,loading capacity,ductility,energy dissipation ability and hysteretic characteristics of the joints were analyzed.The results showed that the loading capacity and the ductility of extended-end-plate connections is the highest,and energy dissipation ability is better than end-plate connection joints,but their stiffness degenerates seriously after ultimate load. |
