摘　　要：由于支撑节点板的存在,将对铰接支撑框架结构中的梁柱节点的转动能力产生影响,梁柱节点的刚度将由铰接过渡到半刚接。本文通过ABAQUS有限元分析软件,分析了节点板的尺寸、厚度对梁柱节点刚度的影响。由于梁柱节点半刚接的影响,结构体系的整体反应及局部杆件内力都将受到影响,通过分析计算,可以发现梁柱节点半刚接对结构体系整体反应影响较小,但是对布置支撑的中间跨梁的弯矩影响则不能被忽略。In the braced frame steel structures, the rotation capacity of beam-to-column hinged joints will be influenced by the gusset plates used at braces ends. For this reason, the influences of the size and thickness of the gusset plates to the stiffness of beam-to-column connections are studied by the program ABAQUS. It was found that the stiffness of beam-to-column joints has a transition from the hinge to the semi-rigid. By the analysis of a 6-story braced frame calculating the beam-to-column semi-rigid joint, it was also found that the subsequent flexural moment of beams in the braced span can not be ignored in design, although the subsequent influences on the stiffness and displacements of stories are neglectable.
