［摘要］正交L形多层砌体房屋在现有建筑中占有相当的比例。一般认为，这类结构的第二级鉴定应采用规范方法进行墙体承载力的验算，《建筑抗震鉴定标准》（GB50023—2009）中的面积率简化方法不再适合。对此类结构的第二级鉴定方法进行了研究，提出了多种计算方法，比较了不同方法间的差异，对面积率简化方法进行了改进，给出了适于手算的面积率简化计算方法。

Abstract:Orthogonal L-type multi-story masonry buildings are widely existed in available buildings. Ordinarily, the design code method of seismic capacity checking for walls should be adopted, the simplified method of area ratio specified in Standard for seismic appraisal of buildings GB50023—2009 is not suitable. The method of second step appraisal method for orthogonal L-type multi-story masonry buildings was studied, several methods was suggested, and the comparison of different methods was also carried on. Finally, an improved simplified method of area ratio was put forward.

Keywords:orthogonal L-type; multi-story masonry building; compound seismic capability index; rotational effect factor
