Develop Design Methodologies and Efficient Details for Triple I-Girder Steel Straddle Caps
Straddle caps are frequently required in congested settings in urban environments that preclude the use of central piers due to intersecting roadways. The research focuses on the behavior of three-girder steel straddle caps that offer solutions for each of these desired configurations. Efficient details that maximize the effectiveness of the straddle cap at resisting bending, shear, and torsion will be developed. The work will result in design methodologies that allow engineers to effectively analyze and design straddle caps to produce economical and structurally-efficient systems.
