摘要：
In order to comprehensively evaluate the seismic behavior of the precast concrete shear wall with rectangular spiral stirrups-constraint grouted corrugated pipe connected to horizontal joints, the full-scale specimens of the shear wall was tested and compared with the cast-in-place specimens through a low-cycle loading experiment. The results show that the (1) the full-scale specimens follow the same failure pattern as the cast-in-place specimens do; (2) due to the existence of horizontal joints, the whole loading processes of the two kinds of specimens are diffe-rent; (3) the hysteresis curves of the two kinds of specimens are both full with similar skeleton curves, and the energy dissipation capacities are also similar; (4) the two kinds of specimens are of the ultimate displacement angles of 1/49 and 1/45 respectively, and the displacement ductility factors are both 4.0, which can meet the ductility requirements; (5) the load capacities of the full-scale specimens at different stages are lower than that of the cast-in-place specimens; and (6) precast concrete shear wall with reasonable horizontal joints is of the ductility, load capacity and seismic energy dissipation capacity similar to those of the cast-in-place specimens. ©, 2014, South China University of Technology.
