To comprehensivly evaluate the seismic behavior of pre-cast concrete shear walls with vertical reinforcement lapping in pore-forming on steel plate connected in horizontal joints, fabricated and cast-in-place concrete shear wall with full scale specimens were tested and compared through quasi-static test. The test results showed that the ultimate failure pattern of the vertical connection in pore-forming on steel plate and the cast-in-place specimen was basicly the same, initial cracks appeared in different positions,the hysteresis curve of the specimen was full, the trend of the skeleton curve was basically the same, the capacity of energy dissipation was also similar; the ultimate displacement angle of each specimen was from 1/55 to 1/43, the displacement ductility factor was from 4 to 5, which met the ductility requirements; and the load carrying capacity of vertical reinforcement lapping in pore-forming on steel plate was lower than that of the cast-in-place specimens. Pre-cast concrete shear wall with reasonable horizontal joints can achieve considerable carrying capacity, ductility and seismic energy dissipation capacity with the cast-in-place specimens.
