摘要
HR-EPS模块剪力墙由于中间有芯肋、混凝土不连续、钢筋和混凝土的粘结作用削弱都会造成墙体截面损伤,因此会直接影响墙体的竖向承载力。通过试验研究和数值模拟相结合的方法对HR-EPS模块剪力墙的轴心受压承载力进行研究。研究结果表明:(1)从开始加载到墙体破坏之前,墙体的侧向位移值变化幅度很小;在试件接近达到破坏荷载时,钢筋和混凝土应变达到最大值,说明轴心受压墙体具有较高的竖向承载能力和抵抗变形的能力;(2)墙体的承载力随着钢筋含量的增加而增加;(3)由模拟和试验测得的荷载-位移曲线及钢筋和混凝土的应变曲线基本吻合,表明通过合理的混凝土本构关系基本能满足模型的要求。同时根据以上研究结果推导出了HR-EPS模块剪力墙受压承载力公式。
The HR-EPS module shear wall with concrete core ribs,discontinuous section damage weakens the bond action of steel and concrete will cause the wall,thereby affecting the vertical bearing capacity of the wall.Through the experimental study and numerical simulation of axial compression on the HR-EPS module of the carrying capacity of the shear wall,the results show these as follows.（1）From loading to failure before the wall,axial compression wall lateral displacement is very small. In the specimen close to the failure load,strain of steel and concrete to a larger value,indicating that the axial compression wall with high vertical bearing capacity and deformation resistance ability;（2）Increase the content of the reinforcement to the wall bearing capacity is increased;（3）The load displacement curves and the strain curves of reinforced concrete and concrete are basically consistent with by simulation and experiment,which shows that the reasonable constitutive relation of concrete can meet the requirements of the model. At the same time,according to the above research results deduced the formula for the bearing capacity of HR-EPS shear wall compression module.
