Seismic Performance of Fully Prefabricated L-Shaped Shear Walls with Grouted Sleeve Lapping Connectors under High Axial Compression Ratio

The grouted sleeve lapping connector called the APC has advantages of high fault tolerance, convenient construction, compacted grouting, and low cost, together with realizing full prefabrication vertical components. In this paper, a quasi-static test two fully prefabricated L-shaped walls connected types cast-in-place wall was carried out under axial compression ratio (0.5) to compare their seismic performance. results indicated that connectors effectively transferred rebar stress in walls, failure modes final crack distribution were basically identical. occurred at root limb, while top due constraint sleeve. bearing capacity, stiffness, ductility, energy dissipation specimen by type-I comparable wall, type-II showed greater ductility. Finally, some suggestions for design components are proposed.
