| 摘 要： | 为了研究型钢高强混凝土短肢剪力墙节点的抗裂能力,以配钢形式、轴压比和梁结构类型为变化参数设计了4个型钢高强混凝土短肢剪力墙节点试件和1个高强混凝土短肢剪力墙节点试件进行低周反复荷载试验,观察试件的受力破坏全过程,并获取其开裂荷载。结果表明:节点破坏先后经历初裂、通裂、极限和破坏4个阶段,开裂荷载约为极限荷载的30%～40%,配钢形式对节点抗裂承载力的影响较明显,增大轴压比对节点抗裂承载力有所提高。在试验基础上提出节点抗裂承载力计算公式,计算值与试验值吻合较好。

| Abstract: | In order to research the anti-crack bearing capacity of steel reinforced high-strength concrete short-leg shear wall joint,4 steel reinforced high-strength concrete short-leg shear wall joints and 1 high-strength concrete short-leg shear wall joint are designed for the low cycle loading test,taking account of the variable parameters of steel type,axial compression ratio and beam type.Test results show that the whole failure process of joints experiences first-crack,full-crack,ultimate and failure successively.First-crack loading is approximately from 30 to 40 percentage of ultimate loading.Different steel type has the obvious influence on the anti-crack bearing capacity.Increasing axial compression ratio can improve the anti-crack bearing capacity of joints.Based on experimental research,the anti-crack bearing capacity formula of joint is proposed,calculated results agree well with test results. |
