带节点板角钢连接梁柱节点试验和初始转动刚度研究

带节点板角钢连接梁柱节点具有较为广泛的应用,但目前对此类节点的力学性能尚缺乏完备的理论和试验研究。在半刚性钢框架研究中,节点板通常被忽略;在设计中往往将此类节点简化为铰接连接或带肋的腹板角钢连接形式。设计了三个试件通过试验对其抗弯性能进行研究;并利用有限元分析软件模拟带节点板角钢连接梁柱节点模型。通过试验和有限元分析,提出了带节点板角钢连接梁柱节点的初始转动刚度,为工程设计和应用提供必要的参考依据。

Research on Experiment and Initial rotation stiffness of Angel Beam - column Joint with Gusset plate

There is wide used of beam-column joint with gusset plate angle connection in engineering, however, the mechanical properties of these joints are still lack of complete theoretical and experimental research. In the study of semi-rigid steel frames, the gusset plates are usually neglected, and these joints are often simplified to hinge connections or other types of connections such as web angle joints with stiffener in the design. In this paper, the bending performance is studied by experiment for three specimens, and the finite element analysis software is used to simulate the beam-to-column joint model. The initial rotational stiffness of beam-to-column joints with angle plates of gusset plate is proposed by experiment and finite element analysis, which provides the necessary reference for engineering design and application.
