Structural Seismic Performance of Prefabricated Steel Plate Shear Wall with High Energy Dissipation
China is located at the intersection of the Pacific Rim seismic belt and the Alpine Mountain-Himalayan seismic belt. Earthquakes occur frequently and with high intensity in China, and the structural damage caused by earthquakes leads to huge casualties and serious economic losses. Steel plate shear wall exhibits satisfying seismic performance which is the key to its application in high-rise buildings and high intensity areas. Meanwhile, the industrialization of new construction requires prefabricated steel plate shear wall structure. In this paper, a kind of prefabricated steel plate shear wall with high energy dissipation is proposed. The finite element study on the seismic performance of the prefabricated steel plate shear wall under low cyclic load was carried out by varying the width-to-thickness ratio of steel connecting plate belt and width-to-thickness ratio of ring damper. The failure modes, hysteresis curves, skeleton curves, stiffness degradation, energy dissipation and displacement ductility coefficients were analyzed. The results showed that the hysteretic curves of the prefabricated steel plate shear wall are relatively full under low cyclic load, and the displacement ductility coefficients are above 8. It is noted that the seismic performance of the prefabricated steel plate shear wall is advantageous. It is suggested that width-to-thickness ratio of the steel connecting plate belt and the width-to-thickness ratio of the ring damper are 3.75 for engineering practice.
