Due to the age and changes of using function, the quality of the building needs to be detected and identified as well as structural reinforcement. On-site detection results indicate that the connections between the filled walls and the steel frame are secure and reliable which can guarantee the filled walls and the steel frame work together effectively. In accordance with the principle of equivalent stiffness, filled walls were replaced with shear walls to establish the model. According to the calculation and analysis of the model under lateral force, the results reveal that seismic performance of structure has been improved significantly. One proposal of a consideration for reinforcement scheme with wall rigidity contribution has been offered, references have been made for similar protective historical building reinforcement cases.Keywords: filled wall; steel frame; anti-seismic; detection; reinforcement作者簡(jiǎn)介：劉國(guó)軍，碩士研究生，Email：sunshow7788@163.com。參考文獻(xiàn)［1］GB 50017—2003鋼結(jié)構(gòu)設(shè)計(jì)規(guī)范［S］.北京：中國(guó)計(jì)劃出版社，2003.［2］DGJ 08-108—2004優(yōu)秀歷史建筑修繕技術(shù)規(guī)程［S］.上海：同濟(jì)大學(xué)出版社，2003.［3］BS 4360∶1990 British standard specification for weldable structural steels［S］.
