中文摘要：

钢结构由于设计、施工、使用、损伤以及火灾、地震等影响可能导致构件宏观开裂或失稳，甚至造成工程事故。本文总结了钢压杆稳定加固的理论和试验研究成果。首先对国内外钢压杆稳定加固的现状及其进展进行总结，接着详细介绍了有关纤维、外粘钢和套管加固的理论和试验研究，最后对稳定加固的研究进行了展望。

英文摘要：

Cracking, instability and even engineering accidents of a steel structure may be produced during its design, construction, member damage, fire disaster and earthquake. This paper provides a review of stability theory and experiment research on steel compression bars strengthened. A summary of existing work and development on the stability reinforcement of steel compression bars at home and abroad are first introduced. Then theory and experiment research on steel compression bars strengthened with FRP, bonded steel plates and sleeve pipe are described in detail. Finally, the study of strengthening steel compression bars in the near future is prospected.
