摘要：

To study the seismic performance of prefabricated and pre-decorated modular building joints, two groups of double-wall joints and one group of four-wall joints were tested under low cyclic loading, and compared with cast-in-place shear walls in terms of failure mode, hysteretic performance, ductility and energy consumption. The results showed that when the axial compression ratio is 0.4，the bearing capacity of the double-split shear wall specimen is significantly improved but its ductility coefficient is only 58.53% of that of the cast-in-place shear wall specimen. The energy dissipation capacity and ductility of the double-split shear wall specimen are decreased by 5.5% and 3.4%，and the yield load and ultimate load are increased by 7.9% and 5.6% respectively，compared with the cast-in-place shear wall when the axial compression ratio is 0.1. Due to the existence of vertical and horizontal grouting joints，the four-split shear wall has poor integrity，fast cracking rate and poor bearing capacity. © 2023 Editorial Board of Jilin University.
