Severely Skewed Prestressed Beam Bridge Analysis






An Insider's Perspective: Gary Gardner


Speaker Information


Purpose of the Webinar
Analysis of a Severely Skewed Prestressed Beam Bridge

The presentation discussed modeling of a severely skewed pre-stressed beam bridge using refined analysis and construction stages. A case study presented of a bridge under design for the $429 Million Portsmouth Bypass PPP Project. The bridge features a 170 foot long single span with lightweight concrete beams and a 71 degree skew. The effects of skew on the concrete beams, intermediate steel diaphragms and concrete end diaphragm were discussed and compared to line girder analysis with typical AASHTO skew correction factors.
