Paper “Parametric Study of Skewed Steel I-Girder Bridge Truck Live Load Response” has appeared in the Journal of Bridge Engineering. This paper evaluates the effect of bridge geometric parameters — including skew of 0°–70°, bridge width ranging from 8 to 26 m (27-84 ft), and abutment type (stub versus integral) — on skewed steel I-girder bridge response through a numerical parametric study (using field-validated models), considering live load positioning across the width of a bridge. The distribution of girder strong-axis and lateral bending stress was analyzed, with peak stress compared to standard Line Girder Analysis calculations.

This paper documents a portion of project ICT R27-194 (“Evaluation of Spatial and Temporal Load Distribution in Steel Bridge Superstructures”).
