钢管混凝土中对于梁节点的认识

On the understanding of the beam joint in the concrete filled steel tube

介绍了有限元计算和荷载试验中得到的钢管混凝土柱环梁节点的力学性能和破坏形态,归纳了现有的适于工程实际应用的抗弯、抗剪承载力设计方法以及环梁和框架梁配筋要求,并对带楼板环梁节点的楼板配筋进行了探讨。

The paper introduces the mechanical properties and the failure mode of the ring beam joint of the concrete filled steel tubular column in the finite element calculation and the load test, summarizes the existing design method of the bending and the shear capacity suitable for the engineering practice, the distributed steel requirement of the ring beam and the frame beam, discusses the reinforcement of the floor with the floor ring beam joint.
