Abstract： To study the seismic performance low-yield point corrugated double-layer steel plate concrete composite shear walls，a finite element model was constructed using ABAQUS. The main parameters considered were the form the steel plates （corrugated steel plates flat steel plates） the strength grade the steel （low-yield point steel ordinary steel）.The results showed that the yield load the corrugated steel plate specimens was 11.28% higher than that the flat steel plate specimens，the peak load was 11. 29% higher， the ductility was 18.68 % higher. Moreover，the stiffness degradation the corrugated steel plate specimens was more gradual， their energy absorption capacity was stronger，resulting in better seismic performance. Compared with the ordinary steel specimens，the low-yield point steel specimens reached yield earlier had a certain decrease in bearing capacity，but their ductility was greatly improved，with the maximum improvement being 67.63% the minimum improvement being 44.22% . Their energy absorption performance was more outsting， their seismic performance was beter.In other words，both the structural change the material change can improve the seismic performance the specimens， the combination the two can achieve a greater improvement in the seismic performance the specimens.

Key words： corrugated steel plate；low yield point steel；composite shear wall； seismic performance

双钢板混凝土组合剪力墙由于可以弥补高层及超高层建筑中传统钢筋混凝土组合剪力墙厚墙体、大自重、弱变形的缺点[1-2]，而被应用于一些地标性超高层建筑中，如广州周大福金融中心[3]、盐城广播电视塔[4]等。（剩余7210字）
