Three precast concrete walls, reinforced by weakly bonded ultra-high strength (SBPDN) rebars within their edge zones, were fabricated and tested under reversed cyclic lateral load to investigate effects of anchorage detailing of SBPDN rebars in wall-base joint and embedment length of SBPDN rebars on seismic behavior of precast concrete walls. Experimental results have indicated that if the embedment length of sheath duct housing SBPDN rebars was five times its diameter, the precast concrete walls reinforced by SBPDN rebars could exhibit as high drift-hardening capability as the cast-in-site shear walls.
