A review of the fatigue limit for steel bridges under Ontario highway traffic loading

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