Research on Damage Mechanism and Structural Optimization of Joints in Cavity Shear Wall Structure

Abstract After pouring concrete precast cavity shell structure has been developing rapidly in recent years, compared with cast-in-place structure, the new fabricated low cost, high construction efficiency, and advantages of green environmental protection, shear wall is most widely used, which includes prefabricated plate shell, annular tendon layout, cast-in-situ important process. But by several times stress casting overall disposable forms have obvious differences, including layered interface, material cross section damage caused stiffness degradation, eventually results decrease carrying capacity. In this paper, mechanism analyzed, optimization method connecting parts studied discussed.
