Seismic performance of precast shear wall with sleeves connection based on experimental and numerical studies

The seismic behavior of a full-scale precast reinforced concrete shear wall (PRCSW) endowed with single-row grout-filled sleeves connection, which was developed for six-story precast box-modularized structures with reinforced concrete shear walls (PBSRCSWs), is investigated in this paper. In order to accurately reproduce the axial-flexure-shear boundary conditions of PRCSW specimens under quasi-static loading, this paper proposes a force-displacement mixed control method. Relevant experimental results showed that desired axial forces, rotations and lateral deformations were effectively accomplished on the specimens. Moreover, the PRCSW specimen resembled the cast-in-situ shear wall specimen in terms of failure modes, interstory drift angle, ultimate force, ductility and dissipated hysteretic energy. In particular, the maximum interstory drift angle of the PRCSW specimen reached 17.86 mrad. Finally, experimental results and numerical simulations indicated that the proposed grout-filled sleeves connection method can be safely employed in six-story PBSRCSWs.
