摘　　要：构造复杂的抗震措施在村镇建筑中难以实现,经济实用的消能减震技术是提高村镇建筑抗震性能的有效措施,针对该实用技术设计消能减震墙体进行了低周反复加载试验,并采用Abaqus有限元建模分析、试验和分析,结果表明:墙体在试验过程中一直处于弹性状态,没有产生任何裂缝,明显提高了墙体的变形能力和塑性耗能能力,该实用技术具有良好的消能减震效果,同时得出试验和数值模拟分析结果吻合.Aseismic measures of a complex structure are not applicable for rural buildings. Economical and practical slip damping technology is an effective measure to improve the seismic performance of rural build- ings. In this study, a wall with a sliding layer of asphalt-sand was designed based on such a practical tech- nology, and a pseudo-static test was conducted. The ABAQUS soft was used to analyze the pseudo static test of the wall. The results showed that the wall remained in an elastic state in the process of the test and produced no cracks. Its deformation ability and plastic energy dissipation capacity were obviously im- proved. The results demonstrated the feasibility of the slip damping technology. The analysis results were in good agreement with the experimental results.
