为研究空间剖分T型钢半刚性梁柱连接节点的抗震性能,以框架边柱节点为研究对象,对2个空间剖分T型钢连接节点模型、2个平面剖分T型钢连接节点模型和1个空间刚性节点模型进行了以柱端为加载模式的空间拟静力试验.通过试验现象分析了不同节点变形特性、塑性发展及破坏模式;分析了不同节点的强度、转动刚度、滞回特性、延性系数和耗能特性,研究了空间剖分T型钢连接节点与空间刚性节点和平面剖分T型钢连接节点的受力差异性.研究成果表明:空间半刚性节点在空间荷载的作用下,相关的力学特性均受到不同程度影响.
In order to study the seismic performance of space-splitting T-beam semi-rigid beam-column connections, two frame-split T-section steel connection nodes, two plane-split T- A spatial pseudo-static test was carried out on a rigid-space model with column ends as the loading mode.The deformation, plasticity and failure modes of different joints were analyzed by the test phenomenon.The strength, rotational stiffness and hysteresis of different joints were analyzed, Ductility coefficient and energy dissipation of the T-shaped steel, the force difference between the space division T-steel connection node and the space-rigid node and the plane-section T-section steel connection node is studied.The research results show that the space semi-rigid node under the action of space load is related to The mechanical properties are affected to varying degrees.
