Abstract:
In order to study the seismic performance of shear wall with prefabricated concrete(PC)infilled wall, quasi-static cyclic loading tests on eight 1/2 scaled shear wall specimens were completed, and the failure mode, hysteresis curve, skeleton curve, stiffness, energy dissipation and ductility of specimens were investigated. The results shows that the wall specimens filled with window openings are prone to bending and shear failure, and shear wall failure becomes more severe. Compared to the specimen without infilled wall, the ultimate bearing capacity and stiffness of the infilled wall specimen are significantly improved, and the hysteresis curve is generally in a bowed shape. The energy consumption and ductility of the specimen with door are not much different from that of the pure shear wall. The ductility of the specimen with window is not significantly different from that of pure shear wall, but the energy consumption of the specimen has been significantly improved. When considering both the door and window, the failure mode of specimen is the same as that of the single window specimen, the energy consumption is reduced, and the ductility is the same as that of pure shear wall specimen. The window provides sufficient deformation capacity, while the window sill provides greater stiffness and bearing capacity. Compared to the cast-in-place structure, the infilled wall structures is less integrated, ant it is unable to fully utilize the energy dissipation capacity of material. When there is too much filling in the wall, the energy dissipation capacity of the unfilled wall specimen is actually greater than that of the specimen with both door and window openings filled in the wall.
