摘　　要：为系统研究叠合板式混凝土剪力墙,并为制定地方行业标准提供可靠的科学依据,设计了两种不同边缘约束措施的叠合板式剪力墙模型4个和普通剪力墙模型2个进行试验研究,在恒定的竖向荷载下,进行了施加水平低周反复荷载的叠合板式剪力墙和普通墙体抗震受力性能对比试验,分析了结构的滞回特性和耗能能力,并基于能量原理,对地震总输入能中的阻尼耗能进行了分析,计算出试件的粘滞阻尼系数.试验结果表明,两种不同边缘约束措施的叠合板式剪力墙的耗能无明显差异,叠合板式剪力墙试件与普通剪力墙试件的耗能能力和粘滞阻尼系数也无显著差异,在进行动力分析计算时,叠合板式剪力墙粘滞阻尼系数可与普通剪力墙取值相同.To study the superimposed slab shear walls and provide the reliable scientific basis for the local standards, four superimposed slab shear walls with edge restricted measures of two different forms and two general shear walls were designed. Comparason of the seismic performance on superimposed slab shear walls with two general shear walls under combined constant vertical load and low cycle lateral load were conducted. Hysteresis property and energy dissipation were analyzed systematically. Based on energy method, the damping energy dissipation in the total input energy has been studied and the damping coefficient has been worked out. The experimental results show that the seismic behaviors of the superimposed slab shear walls with concealed columns of two different forms. The energy dissipation and damping coefficient of superimposed slab shear walls and general shear walls are also similar. The damping coefficient of superimposed slab shear walls is the same as general wall for dynamic analysis.
