摘　　要：基于室内1:3缩尺夯土墙的低周反复荷载试验,采用ABAQUS有限元软件对采用不同构造措施的夯土墙进行数值模拟,对比分析了不同构造措施夯土墙的水平承载能力、变形能力等抗震性能的提高程度。结果表明,在夯土墙体中设置一定的构造措施可以改善墙体的受力特性,增强墙体的变形性能和耗能能力,提高墙体的抗震性能。在保证墙体抗屈服和抗剪能力不减弱的情况下,考虑施工繁简和成本,建议优先选择设置混凝土构造柱和三道拉结筋的夯土墙作为承重墙体。Based on the indoor low cyclic reversed loading test of 1∶3 scale rammed earth wall, the rammed earth wall with different construction measures was used to numerical simulation by ABAQUS finite element software, and the degree of improvement in seismic performance such as the horizontal bearing capacity and deformation capacity of rammed earth wall with different construction measures were compared and analyzed. The results show that setting certain structural measures in the rammed earth wall can improve the force characteristics of the wall, enhance the deformation performance and energy dissipation capacity of the wall, and improve the seismic performance of the wall. Under the circumstance of ensuring that the yield resistance and shear resistance of the wall are not weakened, considering the complexity and cost of construction, it is recommended that the rammed earth wall with concrete structural columns and three tie bars should be selected as the load-bearing wall.
