STUDIES OF SKEWED CONCRETE BOX-GIRDER BRIDGES

Analyses of 51 mathematical models using the finite element analysis program CELL were undertaken to describe the behavior of common skewed, concrete box-girder bridges. An assessment was made of effects on structural behavior of varying superstructure width to span length (aspect) ratio, number of cells, skew angle, type of loading, and depth. Span length and skew angle were found to be the most significant parameters influencing girder shear distribution. Aspect ratio and skew angle affected longitudinal bending moments to the largest extent. Based on the results of this study, methods for shear and bending design of skewed bridges are presented. /Author/
