Experimental Study On Tensile Property Of Frp Cable On Sea-Crossing Cable-Stayed Bridge Under Multi-Factors Coupling Aging Action

Aging tests of FRP cable have been carried out taking into account multifactorial influences including preloads, UV radiation, damp heat and salt spray aging. The tensile properties and microstructure of fiberglass cables have been tested for the analysis of the fracture mechanics of the cables. Based on the test results, the influence of multifactor effects on the long-term characteristics of fiberglass cables is analyzed. This study could improve the use of fiberglass cables on cable-stayed bridges across the sea, which will have important theoretical and applied value in engineering.
