在试验的基础上对SRC节点中箍筋作用和无箍筋SRC节点的可行性进行分析,研究无箍筋SRC加厚腹板节点滞回性能和承载力,结果表明,无箍筋加厚腹板SRC节点的变形能力和延性性能能够满足建筑结构的要求,在那些不便于再配置箍筋的节点中,可以考虑省去箍筋。提出加厚腹板强度利用率的概念,并提出无箍筋加厚腹板SRC节点的承载力计算公式及其补强措施。 On the basis of the experiment, the stirrup effect and the feasibility of the stirrup-free SRC joints in the SRC node are analyzed to study the hysteresis performance and bearing capacity of the stirrup-free SRC thickened web joints. The results show that there is no stirrup thickening belly. The deformability and ductility of the SRC nodes of the board can meet the requirements of the building structure. In the nodes that are not easy to reconfigure the stirrups, the stirrups can be omitted. The concept of strength utilization ratio of thickened webs was put forward, and the calculation formula of the bearing capacity of SRC joints with thicker webs without stirrups was proposed and its reinforcing measures were proposed.
