Abstract

Abstract

The problem of determining the allowable axial load ratio of concrete shear wall has not been completely solved.Through theoretical analysis and numerical calculation,the allowable axial load ratio of the rectangular crosssection shear wall without confined boundary elements has been studied.The results show that,to the given compressive ultimate strain of concrete,the aspect ratio and the target top displacement ratio are main factors which influence the allowable axial load ratio of the shear wall,the concrete strength,the strength and the ratio of vertical distribution reinforcement are less.Accordingly,a method of determining allowable axial load ratio in accordance with the aspect ratio and the target top displacement ratio is proposed.The method is simple and practical,it can also be used for revising the design code.
- reinforced concrete shear wall,
- allowable axial load ratio,
- compressive ultimate strain of concrete
