摘要
结构加固的目的,就是要提高结构及构件的强度、刚度、延性、稳定性和耐久性,满足结构安全的要求,改善结构使用功能,延长结构使用寿命。针对工程质量缺陷的修复加固,研究和分析了钢筋混凝土结构外包粘钢加固技术进行加固的实例,介绍了用结构胶粘结混凝土外包粘钢短柱的试验,对加固技术需要改进和发展的方面进行了总结,提出了良好的建议,为今后加固技术发展方向和趋势提供参考。
The purpose of structure reinforcement is to improve the intensity.stiffness.lengthening.stability and durability of the structures and components, to meet the need of security, to improve employ function of the structure, to prolong the life of structure. To repair and strengthening of the quality defect, the paper studied and analyzed the strengthening technology of outer-packing stick steel, introduced test of short columns by outer-packing steel stick concrete with high-strength gelatinization, summarized strengthening technology of which need to improve and future direction, put forward a good proposal for the future direction and trend of strengthening technology.
