摘要：
To improve the safety and construction convenience of the assembled monolithic concrete shear wall with horizontal joints, an innovative connection method of post-cast strip with X-shaped oblique reinforcement was proposed. Three precast specimens and a cast-in-place specimen were tested and compared under the quasi-static test to investigate the influences of post-cast strip with different heights on the seismic performance of precast specimens. Results show that the failure pattern of the precast specimens is nearly the same as that of the cast-in-place specimen. Lateral bearing capacity of the precast specimens is smaller than that of the cast-in-place specimen. The deformability and ductility of specimen PC-1 are relatively better and the seismic requirements can be satisfied. Deformability and ductility of PC-2 and PC-3 are poorer than that of the cast-in-place specimen. The post-cast strip of the wall bottom has impact on seismic performance. Assembled monolithic concrete shear wall with reasonable horizontal joints can achieve the seismic performance similar to that of the cast-in-place specimen. © 2018, Editorial Board of Journal of Tianjin University(Science and Technology).
