COMPOSITE CYLINDER STRENGTHENED WITH GFRP LATTICES UNDER LATERAL IMPACT LOAD

Abstract

Abstract: In this paper, lateral impact resistance of lattice-reinforced composite bridge anti-collision device is studied by experimental method. The spacing of transverse lattice effects of the impact ultimate load, maximum displacement and energy dissipation performance of composite cylinders are analyzed. Numerical fitting is carried out according to the test data. The fitting curves of lattice spacing to ultimate load are obtained. The results show that the tighter the transverse lattice in the test, the greater the ultimate compressive load or ultimate impact load.

Key words: composite cylinder strengthened with GFRP lattices, lateral impact load, maximum displacement, energy absorption
