［摘要］新修訂的《建筑抗震鑒定標準》（GB50023—2009）規(guī)定重點設防類的框架結(jié)構(gòu)不得采用單跨框架結(jié)構(gòu)，否則需進行加固。針對單跨框架的震害特征，探討了該類結(jié)構(gòu)的各種加固方法，結(jié)合兩個工程實例進行了不同加固方法的比較，提出了提高單跨框架抗震能力的加固策略。

Abstract:In the Standard for Seismic Appraisal of Buildings (GB50023—2009), single bay frame is forbidden used in major fortification buildings, otherwise it needs be strengthened. Based on the seismic disaster characteristics of single bay frame structures in earthquakes, the methods for improving seismic capacity of single bay frame structures were put forward according to the revised national standard or code.The different strengthen methods of single bay frame structures were studied and compared based on two projects, and the way to improve the seismic ability of single by frame structure was proposed.
Keywords:single bay frame; seismic strengthening; seismic brace; seismic shear wall
