“…(Walbridge et al 2013) investigated the effect of simultaneous truck crossings on the finite life correction factors, as well as the effect of the S-N curve slope (m) on this factor, whichwhile held constant for steel fatigue design at m = 3.0, varies depending on the detail category for the fatigue design of aluminum bridge structures. (Chehrazi et al 2022) obtained fatigue correction factors for bridge elements with very short influence lines, such as expansion joints or orthotropic steel deck panels.…”

In many design codes for roadway bridges, it is required that a design truck be passed over influence lines for stress at various locations on the bridge to obtain nominal stress ranges for design. For the fatigue design of Canadian bridges in the infinite or very long-life domain, the nominal stress range is compared with a fatigue limit, after modification by an appropriate correction factor to account for the difference between the nominal stress range and some measure of the extreme stress range in the expected real traffic histogram, which governs infinite life design. The extent to which the influence of simultaneous truck crossings was considered in the establishment of the correction factors is believed to be limited. With this in mind, a simulation-based study, conducted to investigate the effects of simultaneous vehicle crossings on the fatigue limits for steel bridges under Ontario highway traffic loading, is presented in this paper.
