摘要：
Quasi-static tests of five reinforced concrete shear walls with flange were carried out under cyclic loading. Considering different section forms, loading histories, range and stirrup ratio of boundary element at the free end of web and whether to add boundary element at the web-flange junction, failure mechanism, hysteretic behavior, bearing capacity and deformation capacity were investigated under uniaxial and biaxial loads. The results indicate that the damage to the shear walls with flange is mainly concentrated in the boundary element of the free end of web, while the flange remains intact expect for a few cracks. Hence setting boundary element at the web-flange junction has little effect on the mechanical behavior of the shear walls. The strength and stiffness are higher when the flange is in tension, whereas the ductility and energy dissipation capacity are better and the stiffness degradation is slower when the flange is in compression. The influence of the biaxial load on the bearing capacity and deformation capacity in the web direction is minor. Enhancing the boundary restraints of the web boundary can effectively improve the seismic behavior of the shear walls. © 2017, Editorial Office of Journal of Building Structures. All right reserved.
