Research Progress on the Connection Performance of Precast Reinforced Concrete Shear Wall
The research progress of joint connection performance of precast RC shear wall without protruding reinforcement on the edge is expounded.It is pointed out that the connection form of the existing fully precast RC shear wall with protruding reinforcement at the edge of the wall restricts the construction efficiency and quality to a large extent in the actual engineering.The characteristics and shortcomings of the dry connection of fully precast RC shear wall, the dry and wet connection of semi-precast RC shear wall are discussed by considering that there is no protruding reinforcement on the edge of the precast RC shear wall.It is suggested that the next step should be to improve the bonding quality between the precast and cast-in-place parts of the semi-precast RC shear wall, and study the new connection joint form and the reinforcement connection mode.On this basis, the precast concrete shear wall structure with tenon joint is proposed.Based on ABAQUS finite element software, a double-sided direct shear model is designed and its joint bearing capacity is simulated.
