摘　　要：对3个新型全螺栓端板连接十字节点试件在低周反复水平荷载作用下的滞回性能进行试验研究,研究试件的破坏形态,分析得到了新型全螺栓端板连接十字节点的滞回曲线、骨架曲线、延性和破坏模式等。试验结果表明:随着端板厚度的增加,试件的极限承载力、耗能能力和延性随之减小。新型全螺栓连接节点的破坏模式有3种:分别为端板屈曲、焊缝撕裂和螺栓拔出。The paper studied the hysteresis behavior of cross-joint specimens with all-bolted end-plate connections subjected to quasi-static loading. By observing the failure process of specimens,the hysteresis curves,skeleton curves,ductility and failure mode were analyzed. The test results showed that increasing the thickness of end-plate could decrease the ultimate bearing capacity,energy dissipation capacity and ductility of specimens. There were three failure modes,which were the end-plate buckling,weld separated and bolt pulled out.
