Abstract

Abstract: Fiber reinforced composites have the characteristics of light weight, high strength, good designability, good corrosion resistance, and can be used in the field of bridge anti-collision. In this paper, the isolated anti-collision system of bridge was studied for the fiber reinforced composite winding pipe pile. Bending tests were carried out on fiber reinforced composite winding pipe piles, and the failure modes and force-displacement curves of the winding piles under different winding angles and thicknesses were compared and analyzed. The elastic modulus of the winding pipe pile was calculated according to the test results, and according to the theoretical calculation, a single anti-collision pipe pile with cantilever pile and support pile is designed, and then some design suggestions for anti-collision system of the bent pipe pile were provided.

Key words: fiber reinforced composite, winding pipe pile, bridge anti-collision, bending test, theoretical analysis
