Abstract

Abstract

A new type of prefabricated concrete shear wall, which is connected by the dark beam with a vertical seam, was proposed to reduce the quantity of cast-in-situ concrete in the edge members of the shear wall, and it also can facilitate the construction and improve the assembly rate. In order to verify the feasibility of the new prefabricated shear wall, quasi-static tests were carried out on the prefabricated and cast-in-situ T-shaped shear walls. The influence of dark beam height on the hysteretic behavior, stiffness degradation, ductility and energy dissipation capacity of T-shaped shear wall was studied. The experimental results showed that the failure modes of T-shaped precast shear walls were bending failures for integral component and shear failures for local joint, and the concrete at the bottom of the shear wall away from the flange side was crushed, which was similar to that of cast-in-situ shear wall; the hysteretic curves of shear walls were asymmetrical and very full, which showed a good energy dissipation capacity; comparing with the cast-in-situ shear walls, the bearing capacity of the prefabricated shear walls was reduced, but there was little difference between the deformation capacity and energy dissipation capacity.
