摘要

摘要: 为研究高轴压比钢骨混凝土矮墙的抗震性能,对3片高宽比为0.95的试件进行水平加载试验。试件呈剪切破坏;端部纵筋、竖向分布钢筋以及钢骨翼缘压曲,钢骨腹板出现塑性铰线。端部钢骨能够提高剪力墙的抗剪承载力,但对试件的塑性变形能力影响不大。据此提出钢骨混凝土剪力墙的受剪承载力计算式,计算结果与试验结果吻合较好。

Abstract: To study seismic behavior of SRC low shear walls with high axial force ratio lateral loading experiment of three shear wall specimens with aspect ratio of 0.95 was carried out.Shear failure occurred on all specimens.The longitudinal reinforcements at the wall ends and the distributed vertical reinforcements were buckled.The flanges of the structural steel buckled and the plastic hinge lines were observed on the web.The structural steel increased the shear bearing capacity of specimens.The influence of the structural steel area on the plastic deformation of specimens was not obvious in this test.A shear bearing capacity formula of SRC shear wall was proposed and the calculated results had good agreement with the test results.
