摘　　要：为了较全面的研究村镇自建砌体结构的抗震性能,根据各地区村镇建筑的现状,建立了12个砌体结构的模型,分别考虑了砂浆强度、构造措施、结构布置等因素。通过模态分析和模型弹塑性地震反应分析,研究了影响结构抗震性能的主要因素及各模型在不同设防烈度地区大、中、小地震作用下的破坏情况。结合抗震设计理论及规范,给出了针对不同设防烈度地区村镇自建砌体结构满足最低抗震设防目标的设计建议。In order to comprehensive study to seismic performance of the rural self-built masonry structure, accord?ing to the situation of the regional rural construction, 12 masonry structure model is established in this paper, consid?ering respectively the mortar strength, structural measures and structure arrangement. Through the modal analysis and the elastic-plastic seismic response analysis of the model, it studies the main factors of influencing the structure seismic performance and the damage state of each model under the action of earthquake of different region intensity. Combining the theory and specification of seismic design, it gives design proposal of meeting minimum seismic forti?fication goal for different intensity region rural self-built masonry structure.
