Abstract: To investigate the seismic performance of precast shear wall structure with openings, pseudo-static tests of two precast shear walls with different window-wall heights are conducted. Based on the test results, a refined finite element numerical simulation method is proposed, and the effect of window-walls to the structure is further evaluated. The experimental and numerical simulation results indicate that window-wall can work together with the coupling beam entirety at the preliminary stage. Then, a dual coupling beams mechanism is observed when the abovementioned two components separate. The failure modes of these two specimens involve crushes of the concrete at the plastic hinges formed at the bottom of walls and at two ends of the dual coupling beams. The load bearing capacity and initial stiffness of the specimen with a larger height of window-wall are larger, while its ductility and energy dissipation capacity are smaller. The window-walls can significantly improve the stiffness, load bearing capacity and energy dissipation capacity of such precast structure. Hence, window-walls are required to be considered in the seismic design of precast shear wall structure with openings.
