水泥砂浆面层加固法是砌体结构抗震加固常用的方法之一,但是按照GB 50003—2011《砌体结构设计规范》和JGJ 116—2009《建筑抗震加固技术规程》计算得到的加固后砖墙抗震受剪承载力设计值存在一定差异,某些情况下差异还较大。通过收集相关文献中基于试验数据提出的13个计算公式,并基于这些计算公式对两种规范的计算方法进行适用性分析,给出部分可供工程设计人员参考的一些建议。
Cement mortar surface reinforcement method is one of the commonly used methods of seismic strengthening of masonry structures, but according to GB 50003-2011 “masonry structure design specifications” and JGJ 116-2009 “building seismic strengthening technical regulations” calculated reinforced brick wall There is a certain difference in the design values of the bearing capacity of the seismic shears, in some cases the difference is still relatively large. Based on the 13 calculation formulas proposed in the related literatures based on the experimental data, and based on these calculation formulas, the applicability analysis of the two kinds of calculation methods is given, and some suggestions for engineering designers are given.
