Highlights•Development of force-displacement mixed control methods for controlling both axial forces, rotations and lateral deformations of reinforced concrete shear wall specimens subjected to quasi-static cyclic tests.•The precast reinforced concrete shear walls endowed with grout-filled sleeves connections behaves similarly to the standard cast-in-situ solution with respect to failure mode, interstory drift angle, ultimate force, ductility and energy dissipation capacity.•The proposed single-row grout-filled sleeves connection method is suitable for six-story box-modularized precast reinforced concrete shear walls.•The multi-layer shell element combined with the proposed truss elements at the boundaries is effective for the proper simulation of precast reinforced concrete shear walls endowed with grout-filled sleeves connection.

SummaryThe 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 17.86mrad. Finally, experimental results and numerical simulations indicated that the proposed grout-filled sleeves connection method can be safely employed in six-story PBSRCSWs.
