| 10. | In this thesis , four types of steel beam - rectangular cfst column connections , including normal welded flange plate ( wfp ) connection , bolted flange plate ( bfp ) connection , stiffened end plate ( sep ) connection and double split - tee plate ( dst ) connection , were designed based on the configuration of steel frame connection . total 8 models , 2 models of each kind of connections were tested under low - reversed cyclic loading at the end of cfst columns . the relationships between force and displacement at the end of columns , the relationships between the moment and rotation of the joints , degradations of strength and stiffness , ductility , failure mechanism and failure characteristics of these four connections under different axial - compression ratios were presented
本文借鉴钢框架节点构造，设计了四种类型矩形钢管混凝土柱与钢梁连接节点，包括常规栓焊( wfp )节点、翼缘全螺栓连接( bfp )节点、双t板连接( dst )节点以及加劲端板连接( sep )节点，进行了四类节点8个模型试件在柱端低周反复荷载作用下的抗震性能试验研究，比较了不同轴压比下节点的滞回性能、强度与刚度退化、延性、破坏机理与破坏特征，主要结论有： 1 、节点的位移滞回曲线与转角滞回曲线为块型分布，没有或略有捏拢现象，耗能能力强； 2 、轴压比对节点滞回曲线有显著影响，全部节点都有显著的刚度退化； 3 、位移与转角骨架曲线在峰值荷载后有较长的水平或下降段，具有良好的延性性能； 4 、从整体抗震性能上看，翼缘全螺栓连接节点、双t板连接与加劲端板连接节点都优于常规栓焊节点，可在实际工程中加以推广。 |
