To examine the seismic performance of Monolithic Precast Concrete Shear Wall (MPCSW) structure, a 1/5-scaled twelve-story model is designed and investigated by shaking table test, and connections between the precast elements and their impact on seismic performance of the overall model are comprehensively inspected and analyzed. Based on the testing results, the structural responses are divided into elastic stage and plastic stage, and the variations of dynamic characteristics, cracking and failure pattern, seismic responses of the model are accordingly presented. The experimental results indicate that most of critical cracks of the MPCSW model locate on the coupling beams and horizontal connections of precast concrete shear walls, and the fundamental frequency exhibits a successively decreasing trend during the entire testing process. Furthermore, The MPCSW model is designed in accordance with Chinese codes meets the requirement for the seismic fortification intensity of eight, and shows an adequate safety margin to resist collapse in the case of 0.90 g.
