In order to study the seismic performance of new hybrid precast concrete shear wall (NHPW), the low frequency cyclic loading experiment was carried out on one cast-in-situ and three NHPW specimens with different prestress forces. Compared with the cast-in-situ specimen, the anti-cracking ability, capacity strength and stiffness of NHPW specimens have been obviously improved, the displacement ductility remains similar, and the energy-dissipating capacity is lowered within later load stage. Meanwhile, along with the increase of the prestress force, the specimen stiffness and crack load have been enhanced, residual displacement decreases and the capacity property remains steady. The proposed method for predicting the ultimate stress of unbounded posttensioned tendons possesses high accuracy and the strength capacity design method according to available standard can ensure sufficient safety.
