In recent years, large-span metal roof is often exposed by wind. By analyzing and summarizing the reasons, this paper proposes an intelligent strengthening system for metal roof panel system. The structural health monitoring and distributed optical fiber sensing technology are organically applied to the metal roof reinforcement system. Based on the intelligent material reinforced fiber composite sensing material, which has both stress and sensor, and based on the distributed strain calculation, the high tensile capacity of the reinforced fiber composite sensor material is used to realize that the metal roof panel will not be lifted in the extreme wind days, At least achieve the effect of being lifted and not being blown away. This intelligent reinforcement system of metal roof based on optical fiber sensing technology is applied to the actual project of Xuzhou East Railway Station, hoping to provide reference for similar projects in the future.
