摘要:
提出了一种新型的钢与混凝土组合梁、连续复合螺旋箍混凝土柱的连接节点,这种节点的构造为:组合梁混凝土中的负钢筋贯通节点核心区,而组合梁的钢梁部分靠直筋和X筋连接.钢筋连接的节点不但传力明确,还便于核心区混凝土的浇筑,而且X筋能克服本身的滑移.为了研究该节点的抗震性能和破环机理,对这种节点进行了足尺的拟静力试验,试验表明节点破坏前梁端形成了明显的塑性铰,对节点的强度、延性、滞回性能进行了分析,表明该节点具有较好的耗能能力,同时根据实验提出了节点核心区承载力公式.
Abstract:
A new type of joint of steel-concrete composite beam and continuous compound spiral hoop reinforced concrete column is presented. The joint is constructed such that the reinforced bars in the negative moment zone in the composite beam is linked up and the steel beam part of the composite beam is connected by straight reinforced bars and X shape reinforced bars. This type of joint is explicit in force transmission and convenient in pouring the core zone concrete. X shape reinforced bars is able to overcome the bond slippage between bar and concrete. In order to study seismic behavior and failure mechanism of the joint, the quasi-static test was carried out on full-scale specimens. The test result indicates that the plastic hinge at the beam end was formed before failure. The joint’s strength, ductility and hysteretic behavior were analyzed, and results indicate that the joint has excellent energy dissipation capability. The bearing capacity formula of the core zone is presented according to the test.
