AI Technical Summary
In existing double-sided composite shear wall structures, the difference in lateral constraint between the precast wall panels on both sides leads to an unstable connection between the steel mesh and the truss reinforcement, which reduces the overall seismic performance of the structure.
A connecting assembly with a bent angle at the bottom of the diagonal web reinforcement and two lower chord reinforcements is adopted. A triangular support structure is formed by welding and binding. Tree-like tie rods are staggered between the outer leaf wall panel and the inner leaf wall panel to enhance lateral restraint and connection tightness.
It improves the overall stability and seismic performance of shear walls, avoids connection failures caused by stress concentration, and ensures that the wall can effectively transfer and disperse forces when subjected to forces in different directions, forming a coordinated overall structure.
