Research progress on fire resistance in steel structure building
Due to its high strength,light weight,good shock resistance,low cost of land,small occupation,high degree of industrialization,beautiful appearance and can be reused,the steel structure has been widely applied in high-rise buildings.The steel structure,however,is poor fire resistance,thus,the steel structure for fire protection is of great significance.This paper firstly summarizes the development and advantages of steel structure.Secondly,since the fire protection of steel structure is of great significance,the method of it is introduced in detail in this paper,including cut-off method and grooming method.Among which the cut-off method includes Spraying method,Coating method,Shield method,Water spray method.Various protection methods have their own excellent,shortcomings,people need to choose the most appropriate and the most economical protection method according to the actual situation.
