摘要 在参考试验研究的基础上,建立合理的有限元计算模型,利用建立的有限元模型对加固后墙片进行了计算,分析了混凝土板墙加固砖墙影响因素——水平钢筋配筋率、板墙厚度,研究了这两个因素对于加固后墙片极限承载力以及增强系数的影响。分析结果表明,水平钢筋配筋率是影响加固后墙片抗剪承载力的关键因素之一,在规程中计算参数的取值中应合理考虑水平钢筋配筋率的影响。 Finite element software is used to establish a rational model on the basis of the test firstly.And then the models of the walls are use to expand the calculation about the wall strengthened with concrete splint.By analyzing the results,the authors get the wall's earthquake-resistant capability when they have different ratio of horizontal reinforcement and vertical stress.Based on the analysis,the ratio of horizontal reinforcement is a key factor to the shear bearing capacity of the wall strengthened with concrete splint.In the code,the authors take the ratio of horizontal reinforcement into account.
