| 摘 要： | 为了研究不同数量暗支撑对型钢混凝土剪力墙的抗震性能影响，选取4个剪跨比为1.75的矩形截面型钢混凝土剪力墙试件进行了低周反复荷载下的试验研究（其中1个为普通剪力墙对比试件，3个为工字钢暗支撑剪力墙试件），对比分析了不同数量暗支撑条件下型钢混凝土剪力墙试件的破坏特征、承载力、刚度、延性、滞回特性及耗能能力.试验研究表明:带暗支撑型钢混凝土剪力墙试件的裂缝细密且分布区域较大，塑性铰发展充分，滞回曲线饱满，耗能能力明显提高；带暗支撑型钢混凝土剪力墙试件的屈服荷载和极限荷载相比普通剪力墙分别提高了88.76%和91.97%，极限位移角提高26.67%，抗震能力比对比试件显著提高.

| Abstract: | Three steel reinforced concrete shear walls with concealed bracings and one common concrete shear wall were tested under a low cyclic reversed load condition to investigate the seismic behaviour and the effect of having a different number of concealed bracings. The failure characteristics of steel reinforced concrete shear wall specimens were comparatively analysed. These failure characteristics included bearing capacity, stiffness, ductility, hysteretic behaviour, and energy dissipation capacity. The test indicated that the cracks of steel reinforced concrete shear wall specimens were narrower and distributed more widely than the common shear shear wall specimens. Also, the plastic hinge and hysteresis curve developed more fully, and energy dissipation capacity was improved significantly. Compared to a common shear wall, the yield load and ultimate load of the steel reinforced concrete shear wall were increased by 88.76% and 91.97%, respectively. In addition, the limit displacement angle was increased by 26.67%. Furthermore, the seismic capacity was improved significantly. |
