Research on Fatigue Load Parameters of Steel-Concrete Joint of Bridge Used for Highway Traffic and Light-Rail Traffic

Abstract:

This paper presents the calculation method for fatigue load parameters of light-rail traffic of the steel-concrete joints of Caiyuanba Yangtze River Bridge. Based on that the light-rail vehicles meet conforms to the normal distribution assumption, rain-flow counting method is adopted for the internal force amplitude of the steel-concrete joint induced by the light-rail traffic, which is then equivalent to fatigue load of constant amplitude according to linear cumulative damage criterion from Miner. With regard to design and research for similar bridges, this method can be referred to.
