Abstract
Low cyclic loading tests were carried out for one precast two-way hollow slab shear wall with cast-in-situ boundary elements and one RC shear wall. The seismic performance of precast two-way hollow slab shear wall was analyzed. The test results indicated that macroscopic vertical cracks appeared along precast slab vertical holes of precast two-way hollow slab shear wall. The failure characteristics of the precast two-way hollow slab shear wall were significantly different from that of the reinforced concrete shear wall. Shear failure could be avoided and seismic performance of the new type shear wall was good.
