摘要: 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。

Abstract: Based on the test data, the function of stirrup in SRC joints and the feasibility of SRC joints without stirrup are discussed, also the hysteretic behavior and capacity of bearing loads of non-stirrup SRC joints with thickened web are analyzed. It is indicated that SRC joints with thickened web and drawing steel set on longitudinal bar of columns can be satisfied with the requirement of deformation capacity and ductility of specimens, and the stirrup in SRC joints has not to be set, which is inconvenient. The utilization ratio of thickened web is put forward, also the formula of bearing capacity and reinforced measure are given.
