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,在设计中往往将此类节点简化为铰接连接或其他类型的连接形式。通过试验研究和有限元分析对其抗弯性能进行研究。对具有3种构造形式的带节点板角钢连接梁柱节点分别进行静力试验和滞回试验,得到每个试件的弯矩一转角曲线和破坏形态;利用有限元分析带节点板角钢连接梁柱节点在力学性能上与其他节点形式的不同。
The beam-column joint with gusset plate angle connection has been widely used in engineering, however, the mechanical properties of the joint were still lack of complete theoretical and experimental research. This kind of joint was often simplified as an articulated connection or other types of connections in the design. The experimental study and finite element analysis were carried out to study the flexural behavior of the beam-column joint with gusset plate angle connection. The moments-rotation curves and failure modes of the three kinds of beam-column joints were obtained by the static test and hysteretic tests. The differences of mechanical properties between the beam-to-column joints with gusset joint and other types joints were analyzed by finite element method.
