Development of Design Criteria for Simply Supported Skew Slab-and-Girder Bridges
Elastic analyses, using the finite element method, were done on 108 single span skew slab-and-girder bridges. Each structure had 5 girders and stiffnesses were representative of bridges with pretensioned I-girders or steel I-beams. Convergence studies to evaluate the precision of the finite element models were also done and comparisons were made with the results of other studies. An extensive parametric study was done to determine the most important variables and to gain an understanding of the response of the skew bridge. Expressions for the design moments in interior and exterior girders were then developed. These take into account the span and spacing of girders, the stiffness of the girders relative to the slab stiffness, and the angle of skew.
