［摘要］新修订的《建筑抗震鉴定标准》（GB50023—2009）规定重点设防类的框架结构不得采用单跨框架结构，否则需进行加固。针对单跨框架的震害特征，探讨了该类结构的各种加固方法，结合两个工程实例进行了不同加固方法的比较，提出了提高单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
