Abstract:In order to ensure the safety and reliability of the application of double-faced superimposed shear wall structural system, in-depth experimental research was conducted on the mechanical performances of double-faced superimposed shear wall structure, and the research content included the seismic performance of double-faced superimposed shear wall, the anchoring performance of vertical connection reinforcement, and the seismic performance of the whole structure. The seismic performances of double-faced superimposed shear walls with different structural details were compared, including different  boundary elements, different distances between reinforcement trusses and whether the lap length of vertical connecting reinforcement is increased by 500mm, and the influences of reinforcement truss and precast layer were analyzed on the bond strength of vertical connection reinforcement, and the seismic performance of the whole structure overlapping connection zone was deeply explored. The results show that the double-faced superimposed shear wall structure with reasonable design has excellent seismic performance and can be widely used.

Keywords:double-faced superimposed shear wall; seismic performance; bond strength; overlapping connection
