Abstract

The structure of shear wall has become one of the most commonly used structures for the present residence in our country. The wide application of the structure of the shear wall structure will play an important role in the deepening development of China's housing industry. For the structure of the shear wall structure, the reliability of the connection between the shear wall panels is the key to the seismic performance of the whole structural system, and it is also an important factor in the application of the assembly shear wall structure. In this paper, through the systematic analysis and comparison of the traditional connection technology, a new connection method is proposed, that is, the longitudinal reinforcement is made into a closed U-shaped bar to complete the connection, which is designed to improve the traditional connection structure, Which is conducive to the promotion of defects, and carried out the seismic performance of the experimental study. A total of two prefabricated shear wall horizontal connection nodes and two quasi-static tests with two joint joints with overlapped floors were used to test the yield and damage of the specimen, the stress transmission of the connected bars and the stress distribution of the complex nodes. The characteristics of the system were analyzed and studied. The test results show that the failure mode of the specimen is the bending shear of the shear wall, and the damage process includes the longitudinal steel yield, fracture, crack expansion and concrete peeling. The stress transfer effect of the longitudinal connection of the shear wall is good, and the whole specimen shows a good energy dissipation effect.
