摘　　要：随着我国经济的高速发展,旧工业建筑出现不符合现代发展要求、不符合持续发展战略等诸多问题,大量既有建筑的结构和功能已不能满足人们的需求,建筑工程的加固有着重要的意义。加固涉及很多因素,加固材料的选择和加固技术的施工将直接影响资金的投入和加固的质量。文章结合1个受火灾的混凝土框架结构,对原有的混凝土梁、板、柱进行承载力等参数测试与分析,通过对过火后结构现状进行调查,分析火灾对构件钢筋、混凝土强度等参数的影响程度,选用合适的加固方案进行加固,并对最终加固施工质量进行验证。With the rapid development of China's economy,there are many problems in old industrial buildings that do not meet the requirements of modern development and sustainable development strategy.The structure and function of a large number of existing buildings can no longer meet people's needs.The reinforcement of construction engineering is of great significance.Reinforcement involves many factors.The selection of reinforcement materials and the construction of reinforcement technology will directly affect the investment of funds and the quality of reinforcement.Combined with a concrete frame structure affected by fire,this paper tests and analyzes the bearing capacity and other parameters of the original concrete beams,plates and columns.Through the investigation of the current situation of the structure after fire,this paper analyzes the influence of fire on the parameters such as component reinforcement and concrete strength,selects an appropriate reinforcement scheme for reinforcement,and verifies the final reinforcement construction quality.
