What values optimize accuracy and efficiency for Maximum Lane-Load Discretization Length along and across the lane?
Discretization on the order of 1/10 span length and 1/2 lane width is typically sufficient for overall superstructure and substructure behavior. Finer discretization may be necessary to capture certain local effects. Since influence analysis can be time-consuming, we recommend using the largest discretization size possible, especially during preliminary analyses, then possibly refining the discretization for final results. To graphically show and evaluate discretization, it may be useful to plot the influence lines for a few representative quantities.
