Study on the Seismic Behavior of Hollow R.C Shear Wall Model Building with and without Seams

Based on the pseudo-dynamic and pseudo-static under low-cycle test of 10-storey model building without seams and 6-storey model building with seams, the change of dynamic characteristics, the failure mechanism, the deformation feature and ductility of two type structures are discussed. The result of experimental study proves that the capacity of hollow shear wall is well; In elastic stage, the hollow shear wall and common shear wall are similar: high stiffness and little deformation; In elastic-plastic stage, the deformation is increasing, and the slit hollow shear wall are divided into several little walls, the property of energy dissipation of hollow shear wall structure is good. The seismic behavior of the slit and integral hollow shear walls are used in the multi-story and low high-rise building.
