Abstract_Chinese:对轻型钢木组合剪力墙抗侧性能进行研究, 设计一个轻型钢框架对比试件, 进行单调加载试验; 两个轻型钢木组合剪力墙试件, 进行低周反复荷载试验; 考察有无OSB板及板厚对轻型钢木组合剪力墙抗侧性能的影响, 研究墙体的破坏形态、抗侧承载力、滞回性能、延性、耗能能力等．研究结果表明, 轻钢龙骨框架中引入常用的OSB板组成轻型钢木组合剪力墙可提高其侧向承载能力, 随着板厚的增加抗侧性能有所提升; 轻型钢木组合剪力墙抗震性能较差, 轻钢龙骨框架与OSB板未能良好地协同变形发挥其组合作用, 可见自攻螺钉未能起到较好的连接作用．建议进一步深入探究其协同工作机理及覆面板材料和厚度等参数的影响规律, 为轻型钢木组合剪力墙工程实际提供参考．
Abstract_English:Study on the lateral resistance performance of light steel-timber hybrid shear wall was carried out in this paper，including a monotonic loading test on a light-weight steel frame specimen for comparison and low cyclic reversed loading tests on two light steel-timber hybrid shear wall specimens. The tests aimed to study the failure mode，lateral resistance，hysteretic behavior，ductility and energy dissipation of the walls，considering the effect of the existence of OSB plates and the plate thickness on light steel-timber hybrid shear wall. The research shows that the use of OSB plate will enhance the lateral capacity of light steel-timber hybrid shear wall and the enhancement action will grow as the plate thickness increases. The seismic performance of light steel-timber hybrid shear wall was not good in which the light steel frame and OSB plate failed to deform consistently and provide combination action，which may result from the poor connection of self-tapping screws. Therefore，it is suggested that a further research should be done about the principle of combination action as well as the effect of panel material and its thickness，which can provide some references for the application of light steel-timber hybrid shear wall.
