摘要

摘要: 为研究套筒灌浆缺陷对装配整体式混凝土剪力墙抗震性能的影响,设计并制作了3个缺陷程度递增的足尺寸剪力墙试件和1个无缺陷对比试件,对其进行拟静力试验并对试件破坏过程、承载力、刚度和耗能能力进行分析。结果表明:相对于无缺陷试件,灌浆缺陷对开裂荷载的影响不大,但会导致试件的滞回曲线产生不同程度的捏缩;随着缺陷程度的增加,试件的屈服荷载、峰值荷载及耗能能力均会下降,屈服荷载分别下降了3%、8%、15%,峰值荷载下降了5%、12%、14%,总能耗分别下降了4%、8%、12%。

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.
