Quasi-static experiments are carried out on four precast concrete shear wall specimens with shear span ratio of 1.39,assembled with reinforcement grouting anchor connection and corrugated pipes.The influence of the reinforcement lap length in the corrugated pipes on seismic performance of precast concrete shear walls is studied in the experiments from the aspects of bearing capacity,ductility and energy dissipation capacity of the experiment specimens.The experimental results indicate that the failure modes...
