Abstract:
Five large-scale flanged reinforced concrete shear walls, including four T-shaped walls and one L-shaped wall, were tested under uniaxial and biaxial cyclic loading. The objectives of the tests were to provide insight into the failure mechanism and seismic behavior of unsymmetrical shear walls, and to investigate the influence of loading procedure, detailing of boundary elements, and section shape on the cyclic response of the walls. All the specimens experienced a flexure-dominant failure with the damage concentrated at the free end of the web. Test results showed that higher bearing capacity and stiffness but significant stiffness and strength degradations were observed for the case with the flange in tension, whereas better energy dissipation capacity and deformation capacity were achieved for the case with the flange in compression. The failure mechanism suggested that special boundary element could be omitted at the web-flange intersection, and optimal design should be conducted for the boundary element of the web opposite the flange.
