Effect of Edge Confinement on Deformation Capacity in the Isolated R/C Structural Walls

전단벽의 단부보강효과에 따른 변형능력의 평가

This paper reports on tests of reinforced concrete shear walls for wall-type apartment structure under axial loads and the cyclic reversal of lateral loads with different confinement of the boundary elements. Confinement of the extreme element by U-stirrups and tie hooks seems to be as effective as closed stirrups. The shear strength capacity seems not to be increased by the confinement but deformation capacity improved.
