Comparative Test on Seismic Performance of Double Steel Plate Composite Shear Wall with Multi Cavity Configuration

为了研究多腔式双钢板混凝土组合剪力墙的抗震性能,本文制作了6片抗震试验构件,进行水平低周反复加载的分组对比试验,观察破坏形态,获取滞回曲线和骨架曲线。进行了钢筋混凝土剪力墙与多腔式双钢板组合剪力墙对比试验分析,开展了钢管混凝土框架-多腔式双钢板组合剪力墙结构体系的抗震试验。研究表明:多腔式双钢板组合剪力墙具有承载力高、结构刚度大、延性好和耗能能力强的优点,滞回曲线饱满,其极限水平位移角约为1/36左右;多腔式双钢板组合剪力墙与钢管混凝土框架两者具有良好的延性匹配性,协同工作,优势互补,钢管混凝土框架作为抗震二道防线可以有效地参与工作。

In order to study the seismic performance of double steel plate concrete composite shear wall with multi cavity configuration,six seismic test members were made in this paper.The group comparative test of horizontal low cycle repeated loading was carried out to observe the failure mode and obtain the hysteretic curve and skeleton curve.The comparative test analysis of reinforced concrete shear wall and double steel plate composite shear wall with multi cavity configuration was carried out,the seismic test of the structural system of CFST frame and double steel plate composite shear wall with multi cavity configuration was carried out.The research shows that the double steel plate composite shear wall with multi cavity configuration has the advantages of high bearing capacity,large structural stiffness,good ductility and strong energy dissipation capacity.The hysteretic curve is full,and its ultimate horizontal displacement angle is about 1/36;The double steel plate composite shear wall with multi cavity configuration and CFST frame has good ductility matching,work together and complement each other.As the second line of defense against earthquake,the CFST frame can effectively participate in the work.
