摘　　要：为研究填充墙对框架结构抗震性能的影响,采用ABAQUS有限元软件对混凝土框架、轻骨料混凝土砌块框架填充墙和多层框架填充墙进行了分析。通过对比结构的破坏模态、滞回曲线、骨架曲线、刚度退化性能和耗能能力等参数,发现轻骨料混凝土砌块框架填充墙受力性能较好,填充墙的加入使结构的抗侧力和变形能力得到改善并提高了耗能能力,提升了多层框架结构的抗弯性能和抗剪性能。轻骨料混凝土砌块框架填充墙绿色环保、可恢复能力强,具有良好的抗震性能。In order to study the influence of infill walls on the seismic performance of infilled in frame structures,the concrete frame,the wall with lightweight aggregate concrete block infilled frame wall,and the multi-story infilled-frame wall were analyzed by the ABAQUS.The structure's failure mode,hysteresis curve,skeleton curve,stiffness degradation performance,and energy dissipation capacity were compared.The results show that the lightweight aggregate concrete block infilled-frame wall has better mechanical performance.Adding an infilled wall inhances the structure's lateral force deformation resistance,and energy dissipation capacity.It improves the bending and shear performance of the multi-story frame structure.The wall with lightweight aggregate concrete block infilled frame is green,environmentally friendly,resilient,and has good seismic performance.
