Abstract

Abstract

For the problems that the root-deck fatigue cracks of orthotropic steel decks with closed ribs located inside ribs were invisible and greatly harmful, the deck root welding fatigue details were divided into RD details (rib-to-deck details) and RDF details (rib-to-deck details crossing floor beams) according to the connected locations of longitudinal ribs and deck, and the finite element method was applied to study the stress influence surfaces of two fatigue details.The transverse frequency distribution of wheelmark, multiaxial loads and pavement-deck interactionwere considered, and the damage characteristics of two fatigue details were analyzed.Analysis result shows that the target details are in the most unfavorable condition when the wheel is right above each of them.In the longitudinal direction, the stress is relatively higher when the distances of wheel load and target details are no more than 0.6 m.In the transverse direction, the wheel load influence ranges of two details are within 1.0 m.When the transverse distribution of wheelmark is considered, the transverse reduction coefficients of equivalent stress ranges of two details in simplified computation are 0.92 and 0.96, respectively.Under the dual-axle and tri-axle loads, the damages of RD details are 2.10 times and 3.21 times of the damage under single-axle load, respectively.It is unsafe to compute the damage by approximately adding the damage of each axis load, so it is suggested to consider vehicle type while assessing the fatigue life.The stress range of each detail obviously reduces when the pavement-deck interaction is considered, and the change will increase with the increase of elastic modulus of pavement.The stress range of deck with 12 mm thickness considering pavement is almost equal to the range of bare deck with 16 mm thickness at the welding root.For the simplified diffusion model of pavement with 45°dispersion angle, when the thickness of deck is no less than 16 mm, the stress range is simultaneously less than the range of soild model considering the contributions of diffusion and stiffness of pavement, and the difference increases with the increase of thickness of deck, so it is slightly risky to simplify the dispersion effect of pavement without considering its scope of application.When the thickness of deck is 18 mm and the contribution of pavement is considered, the fatigue lifes of two details can meet the design requirement of service life, and RDF details are about 67% of RD details in fatigue life.
