框架节点处多数由于钢筋密集导致混凝土振捣不密实等结果,梁柱节点成为异形柱抗震的薄弱部位。本文通过拟静力试验对在节点核心区配置T型钢和槽型钢以及没有任何增强措施的3根异形柱边节点构件进行研究,对比分析这些构件如下的抗震性能:破坏特征、承载能力、滞回曲线及延性。研究结果表明:在节点核心区配置钢骨有助于提高节点的承载力、变形能力和延性性能,能够改善节点在强度及刚度等方面快速破坏的脆性方面的特征,有助于提高异形柱边节点的抗震能力。
Most of the joints in the frame are the result of the concrete vibrating not dense due to the intensive reinforcement, and the beam-column joints become the weak parts of the special-shaped columns in seismic resistance. In this paper, three special-shaped column-edge joint members with T-shaped steel and grooved steel in the core area of the joint and without reinforcement are studied through quasi-static tests. The seismic performance of these members is analyzed as follows: failure characteristics, bearing capacity, Curves and ductility. The results show that the arrangement of steel bosses in the core of the joints can improve the bearing capacity, deformation capacity and ductility of the joints, improve the brittleness characteristics of the joints in terms of strength and stiffness, and improve the profiled edges Seismic capacity of the node.
