Abstract: A low cyclic reversed load test was carried out on two new precast concrete (NPC) and one cast-in-situ short-leg shear wall specimens. Compared with the cast-in-situ specimen, the strength, stiffness, ductility and energy dissipation of NPC specimens were grasped. The test result shows many contents. The failure mode of NPC specimen is obviously different from that of the cast-in-situ one. The horizontal joint is the weak part with a concentrated deformation. The upper precast shear wall remains in a good condition and the failure presented as shear failure is concentrated in the lower precast shear wall. The finite element analysis shows that: the increase of the connect reinforcements of NPC specimens can increase the contact area of concrete in a horizontal joint, reduce the shear stress, and effectively improve the mechanical behavior of NPC shear wall and enhance its carrying capacity and deformation capacity.
