Evaluating the Challenges of Skewed Bridges [B5]

Skewed supports are frequently required to span highways and streams not perpendicular to the bridge alignment and some bridges are sensitive to the construction and design behavior decision. In these cases girders have a tendency to twist or lay over under the self-weight of a skewed and/or curved bridge. This session will look at the challenges encountered during the design and construction of three different projects with varying severity of skew. Included in the discussion will be a consideration of alternate cross-frame layouts to assess the economics of a staggered cross-frame layout versus an in-line layout.
