Abstract

Abstract

Orthotropic steel decks have been widely used in steel bridges due to their small volume weigh, high strength and good applicability of assembly fabrication. The asphalt pavement laying on the orthotropic steel deck can effectively disperse the vehicle wheel loads, and enhance the stiffness of orthotropic steel decks, and release fatigue damage of deck-to-rib welded joints of orthotropic steel decks. However, the effects of asphalt pavement on orthotropic steel decks were affected by the temperature and loading frequency. To determine the coupling effect mechanisms of pavement characteristics, based on the dynamic stress-strain relations, the effects of temperature and dynamic properties on the fatigue damage of deck-to-rib welded joints were firstly analyzed and quantified. The hourly random traffic flow model in a day was established by using the real traffic flow data, then the coupling effects of temperature and dynamic loads on the fatigue damage characteristics of asphalt pavement layers were quantified. The results indicated that when other boundary conditions were the same, the fatigue damage of deck-to-rib welded joints in summer was about 3.7 times as the fatigue damage in winter. The fatigue life assessment without consideration of pavement properties was underestimated. The fatigue life would reduce from 54 years to 47 year after considering the pavement properties.
