摘  要:以实际工程为例,对原结构进行整体计算分析,发现原结构层间位移角超过规范限值,基础承载力不满足,部分框架柱、框架梁配筋不足,底层柱部分轴压比超限。加固方法有加大基础截面,框架柱加固采用加大截面法和外包钢法及粘贴碳纤维方法,框架梁加固采用外包钢粘贴碳纤维法,板通过粘贴碳纤维方法进行加固。改造的难点在于增加升降乐池,原结构拆除后新建结构结合钢结构的方案的优势达到功能要求。改造过程遵循了结构检测、鉴定、加固、改造的设计原则和设计思路。加固改造后该结构满足现行规范标准要求,并且体现了经济性、安全性、适用性,可为类似工程的加固改造设计提供参考。Taking the actual project as an example,the original structure is calculated and analyzed as a whole,the original structure of the maximum elastic interlayer displacement angle does not meet the requirements of the code,part of the foundation bearing capacity is insufficient,part of the frame column,part of the frame beam reinforcement is insufficient,part of the bottom column axial compression ratio exceeds the limit.The main reinforcement methods are enlarging the foundation section,the frame column is reinforced with concrete,steel and carbon fiber,and the frame beam is reinforced with steel and carbon fiber.The board was strengthened by sticking carbon fiber.The difficulty of the transformation is to increase the lift music pool.After the original structure is removed,the new structure combines the advantages of the steel structure scheme to meet the functional requirements.The transformation process follows the design principles and ideas of structural detection,identification,reinforcement and transformation.After reinforcement and reconstruction,the structure meets the requirements of current codes and standards,and embodies the economy,safety and applicability.It can provide reference for reinforcement and reconstruction design of similar projects.
