Analysis on the Sensitivity of Structure in Girder Steel Bridge Deck Pavement

Abstract

Bridge structure has important impact on pavement stress, and previous research often analyses separately which is one of the reason for pavement disease. This paper analyses the sensitivity of structure in girder steel bridge deck pavement with the finite element method, obtaining the changing regularity of maximum transverse strain, maximum longitudinal strain, maximum longitudinal displacement of pavement surface, interlaminar shearing stresses with six kinds of the structure design parameters including bridge roof slab thickness, diaphragm plates distance, U rib width, distance, thickness, girder space under the most unfavorable load. The study can offer help for the determination of bridge structure design parameters.
