Abstract

Abstract

In order to study the influence of sleeve grouting defects on the seismic performance of assembled integral concrete shear wall, three full-size shear wall specimens with increasing defect degrees and a defect-free comparative specimen were designed and produced, and the simulated static test was carried out to analyze the failure process, bearing capacity, stiffness and energy consumption capacity of the specimen. The results show that compared with the defect-free specimen, the grouting defect has little effect on the cracking load, but it will lead to different degrees of pinching of the hysteresis curve of the specimen. With the increase of defects, the yield load, peak load and energy consumption capacity of the specimen will decrease. The yield load will decrease by 3%, 8%, 15%, the peak load will decrease by 5%, 12%, 14%, and the total energy consumption will decrease by 4%, 8%, and 12%, respectively.
- precast shear wall,
- sleeve connection,
