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作者簡介：臺玉紅，博士，Email: cabrsth@126.com。參考文獻［1］GB50023—2009 建筑抗震鑒定標準［S］. 北京：中國建筑工業(yè)出版社，2009.［2］程紹革，史鐵花. 全國中小學校舍抗震鑒定與加固示例［M］. 北京：中國建筑工業(yè)出版社，2010.［3］張熙光，王駿孫，劉惠珊. 建筑抗震鑒定加固手冊［M］. 北京：中國建筑工業(yè)出版社，2001.［4］程紹革，史鐵花，戴國瑩. 現(xiàn)有建筑抗震鑒定的基本規(guī)定［J］. 建筑結構，2011，41(2)：128-131.
