摘要
钢结构已经广泛应用于工业和民用建筑,由于设计、施工和使用管理不当,材料质量不符合要求,使用功能改变,遭受灾害损坏以及耐久性不足等原因,需要对钢结构进行加固设计。近年来,国内外在钢结构加固设计领域开展了广泛的研究,大量的试验研究和数值模拟不断开拓了钢结构加固设计方法,但是我国1996年批准颁布使用的CECS77∶96《钢结构加固技术规范》年限较久,并且仅仅局限于焊接加固等传统方法。对近些年国内外钢结构加固领域的研究工作进行总结,希望能为CECS77∶96的修订提供有价值的参考,同时可供钢结构加固设计工作人员借鉴。
Steel structure has been widely used for industrial and civil construction, but the steel structure reinforcement design is essential owing to inappropriate design, construction, use and management, unqualified material, functional change, disasters damage and durability deficiency. Recently, more studies on steel structure reinforcement have been executed at home and abroad. A large number of experimental studies and numerical simulation continue to develop the steel reinforcement design technology, however, the Technical Specification for Strengthening Steel Structures （CECS 77∶96） approved and promulgated in 1996 is over a long period and limited to traditional methods such as welding reinforcement technology, etc. A great many of researches are summarized, which will provide valuable references for amendment of CECS 77∶96 and more useful views for steel structure designer.
