Abstract
This paper describes an ongoing research program on the seismic resistance performance of the double-wall precast concrete (DWPC) shear wall. Low-cyclic reversed loading test of three new full scale specimens are carried out based on the previous studies. The test results indicate that DWPC shear walls have higher initial stiffness, cracking load, yielding load and ultimate load. The displacement ductility ratios of DWPC shear walls are no less than that of cast-in-situ shear wall. The hysteretic curves of all specimens are plump, and the trend of skeleton curves is basically the same. The seismic energy dissipation capacities of DWPC specimens are close to those of cast-in-situ specimen. All the specimens have shown favorable seismic resistance performance.
