摘要
对10个钢板夹芯混凝土剪力墙试件进行面外受力性能试验,研究其在单向压弯作用下的破坏特征、承载力、刚度、变形能力等结构性能。通过对各个试件的滞回曲线、骨架曲线、承载力、延性系数和耗能能力等抗震性能参数的计算和比较,分析剪跨比、含钢率以及墙体构造方式的变化对墙体面外受力性能的影响。研究表明:钢板混凝土墙试件的面外变形能力很强,墙体的剪跨比、含钢率变化对墙体的承载力和变形能力有影响。
Through external force performance tests of 10 steel-concrete sandwich composite shear wall specimens,the failure characteristics,bearing capacity,stiffness,deformation capacity of each type of specimen under one-way compression and bending loads were studied. Through calculating and comparing of hysteretic curves,skeleton curves,bearing capacity,ductility coefficient and energy dissipation capacity etc of each specimen,the influence on external force performance under shear span ratios,steel ratios,as well as the changes of way of wall structures was analyzed. The studies show that the external deformation capacity of steel-concrete wall specimen is strong enough,and the bearing capacity and deformation capacity of wall are affected by changes of shear-span ratios and steel ratios.
