摘要
Abstract
With the acceleration of urbanization in China,frame structures have been widely used in various types of buildings due to their advantages,such as reasonable stress and flexible spatial layout.Due to various reasons such as materials and construction,when the concrete strength of frame columns is too low,serious defects and other issues affect the safety of the structure,and reinforcement treatment is required.When the frame column is located in the middle layer of a building,compared to other reinforcement methods that need to take root from the foundation and change the overall dimensions,the advantages of replacing concrete reinforcement are highlighted.Before concrete replacement,the replaced column needs to be fully supported and unloaded.Therefore,a mature and reliable support system is particularly crucial.The paper elaborates in detail on the application of a new friction-based steel bracket support system in the replacement of frame column based on the engineering cases,providing references for similar projects.关键词
