Effects of bridge length and span variations in curved integral abutment bridges

This paper presents the results of a parametric study that focused on the effects of bridge length and span variations on the maximum stress intensity (stress concentration) in the piles of horizontally-curved steel I-girder integral abutment bridges. Over 1,700 three-dimensional nonlinear finite element models with bridge lengths up to 365 m (1200 ft) were analyzed as part of this study. The results indicate that the...
