摘　　要：农村房屋抗震是我国防震减灾工作的重要内容。砖砌体结构作为农村房屋的主要结构形式,如何提高其抗震能力具有重要研究意义。为研究砂浆强度、构造措施和窗洞口对砖砌体抗震性能的影响,该文首先对农村砖砌体房屋常用的几种砂浆和砖砌体进行了抗压强度试验,得到了相应材料及构件的强度参数;然后对不同砂浆强度、不同构造措施和开洞的12个墙片进行了拟静力试验,对比分析了不同因素对墙体力学性能影响。试验结果表明,砂浆强度影响最大,构造措施和开洞影响次之。最后依据试验分析结果为我国农居防震减灾工作提出建议。该文相关研究可为农居的抗震设防、标准制定以及施工提供参考。The protection of rural housing is an important aspect in earthquake prevention and mitigation in China. To improve the aseismic capacity of brick masonry structures, a dominant structure format of rural housing in China, hence becomes very significant. To study the influence of different mortar strength, construction measures and window openings on seismic performance of brick masonry structure, this study firstly introduced the compressive strength test of several normal mortar and brick masonry used in brick masonry buildings. Subsequently, with different mortar strength, different construction measures and openings in the walls, pseudo static tests of twelve walls were conducted and the influence of different factors on the wall mechanical properties was analysed. The test results showed that the mortar strength has greater effects than the construction measures and open hole. Finally based on the experimental analysis results, the suggestions on earthquake disaster preparedness and mitigation for rural housing were proposed. This study is expected to provide guidance for seismic fortification, standard formulation, and construction of residential housing in rural China.
