【Abstract】 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.更多还原
