摘　　要：提出了钢筋混凝土带暗支撑剪力墙 ,进行了 11个 1 3缩尺的低矮剪力墙模型的低周反复荷载试验 ,重点分析了暗支撑的倾角和配筋比对剪力墙抗震性能的影响 ,给出了带暗支撑剪力墙承载力的计算方法 ,计算结果与实测结果符合较好。In this paper, the RC shear wall with concealed bracings is brought forward and the cyclic loading tests of eleven 1/3 scale low-rise shear walls are carrie d ou t. The influence of steel ratio and obliquity of concealed bracing on aseismati c propcrty of shear wall is emphatically studied in this paper. The formulas of calculating of the load-carrying capacity are also establi shed and the calculating results and the testing results are in good agreement. Finally, some suggestions on the aseismatic design of RC shear wall with concea led bracings are proposed.
