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作者简介：刘国军，硕士研究生，Email：sunshow7788@163.com。参考文献［1］GB 50017—2003钢结构设计规范［S］.北京：中国计划出版社，2003.［2］DGJ 08-108—2004优秀历史建筑修缮技术规程［S］.上海：同济大学出版社，2003.［3］BS 4360∶1990 British standard specification for weldable structural steels［S］.
