Abstract

Abstract

Axial load ratio is a main factor affecting the seismic performance of concrete structural walls.However,the influences of ductility demand and the characteristic value of stirrup content in boundary elements are not considered in the allowable axial load ratio specified by the current codes in China.The influence of the characteristic value of stirrup content _v on the displacement ductility ratio _ and allowable axial load ratio,n,for concrete structural walls is studied.It is obtained that the relationships among the ductility ratio,axial load ratio and the characteristic value of stirrup content.The results show that increasing the boundary confinement ratio of the walls can raise allowable axial load ratio.At last,allowable axial load ratio is proposed with various confinement ratios,which is satisfied for certain ductility demand.
- ductility,
- concrete structural walls,
- volumetric ratio of confinement steel,
- axial load ratio
