摘要：针对村镇建筑垃圾问题，以再生骨料替代部分天然骨料研发出一种新型的再生双通孔抗震砖。采用ABAQUS有限元分析软件，对再生双通孔抗震砖砌体结构在受静力荷载作用时的受力与变形进行分析，由此针对模拟试验楼进行结构地震动受力分析。结果表明：在静力条件下，结构的变形及应力是正对称的；在地震动条件下，再生双通孔抗震砖砌体与传统烧结黏土砖砌体结构相比，其结构剪力、变形都很小；砌体结构地震反应以低阶振型反应为主，结构的主要变形为剪切变形。

Abstract：A new type of wall material was developed by replacing partial of the natural aggregate with regenerated aggregate for the problem of garbage in villages and towns. The ABAQUS finite element analysis software was used to analyze the stress and deformation of the regenerated double-hole anti-shock masonry structure under static load，and the structural ground motion force analysis was carried out for the simulation test building. The results show that under static conditions，the deformation and stress of the structure are positively symmetric，under the condition of ground motion，the structural shear force and deformation of the regenerated double-hole seismic-resistant brick masonry structure are small compared with that of the traditional sintered clay brick masonry structure. the seismic response of masonry structure is always dominated by the low-order vibration response，and the main deformation of the structure is shear deformation.
