摘　　要：针对既有框架结构改RC-钢框架混合结构的改造,提出混合结构新增夹层的构造设计方案,提供结构抗侧刚度以及附加阻尼比的技术措施,并提出构件层面的各种加固设计思路。针对加固改造施工,提出既有结构的拆除、植筋、新增土建构件、新增悬臂柱的逆施工技术等措施,为后续大空间大跨度混合结构的设计和施工提供技术解决参考。In view of the transformation of existing frame structure into RC-steel frame hybrid structure,this paper puts forward the structural design scheme of adding interlayer in hybrid structure,provides technical measures of lateral stiffness and additional damping ratio of structure,and puts forward various reinforcement design ideas at component level.According to the reinforcement and reconstruction construction,some measures are put forward,such as the demolition of existing structures,planting steel bars,adding new civil components,adding new cantilever columns and other reverse construction techniques.It provides technical reference for the design and construction of large-space and long-span hybrid structures.

关 键 词：大跨度 混合结构体系 逆做法 抗剪植筋
