摘　　要：为对叠合混凝土墙板进行较为系统的分析研究,并为编制地方行业标准提供可靠的科学依据,进行了在低周反复荷载下的叠合板式剪力墙和普通剪力墙对比试验研究.较系统地分析了结构的破坏形态、延性、刚度、耗能等,并采用基于刚度的破损指标和基于位移及耗能的破损指标的计算模型对构件进行了计算分析比较,计算结果与试验现象吻合良好.基于刚度的破损指标计算较为简便,可优先考虑使用.To conduct systematically analytical study to this shear walls and to provide reliable scientific basis for the local standards,comparative experimental studies on superimposed slab shear walls and general shear walls under low cyclic loading were conducted.The structural failure feature,ductility,stiffness,energy dissipation were analyzed systematically.The seismic damage model based on stiffness and the seismic damage model based on displacement and energy were analyzed.The calculating results are in good（agreement） with the experimental phenomenon.The seismic damage model based on stiffness computed is more easy and could be used first.
