摘要
应用等效体积单元(Representative Volume Element简称RVE)方法对3片土坯墙体试件的低周反复加载试验进行数值计算分析,并与试验结果进行对比,验证了RVE方法应用于土坯墙体的合理性。在此基础上,对钢丝网水泥砂浆加固的土坯墙体采用二次RVE方法进行数值计算,分析土坯墙体加固前后的抗震性能,验证了钢丝网水泥砂浆加固土坯墙体的有效性与二次RVE方法应用于加固土坯墙体数值计算的可行性。研究成果可为村镇传统生土建筑的改造与抗震加固设计提供参考依据。
In this paper,the low frequency cyclic loading test on the three adobe walls is carried out,and then the numerical simulation is performed using the approach of representative volume element（ RVE）. By comparing the two results,the reasonability of RVE applied in adobe wall is verified. On this basis,the way of secondary-RVE is adopted to apply to the numerical simulation in adobe wall strengthened with ferrocement mortar. Through the analysis of seismic performance of adobe wall before and after being reinforced,the effectiveness of adobe masonry strengthened with ferrocement mortar and the feasibility of secondary-RVE applied in reinforced adobe wall are verified. The results of the research can be used as the reference for the rebuilding and anti-seismic reinforcement of traditional abode buildings in rural.
