Glass fiber reinforced polymer (GFRP) is a new kind of composite material, which combines the advantages of steel bar and concrete, and has the advantages of high strength, strong corrosion resistance and anti-fatigue, etc. In recent years, it has been more and more applied in civil engineering, port, channel and coastal engineering, bridge engineering and other special structures. GFRP material can significantly improve the corrosion resistance of concrete material, and solve the problem that concrete material is prone to corrosion and lead to structure failure in complex environment. At present, the technology is developing rapidly at home and abroad, but in our country, to really apply it widely in engineering construction, we need to further study and analyze the properties of GFRP pipe - concrete composite structure. In this paper, it is concluded that with the increase of eccentricity, the bias bearing capacity of the specimen decreases gradually. With the increase of concrete strength grade, the ultimate bearing capacity is improved. The concrete grade has a great influence on the performance of the specimen. The higher the concrete strength, the stronger the bearing capacity of the structure. The bending performance of GFRP tube composite structure is good.
