The overall objective of this project is to comprehensively investigate the mechanics of shear buckling behavior in slender webs of welded steel plate girders, thus leading to (a) new predictive models that capture the true mechanics, and (b) design modifications that increase economy, robustness, and life-cycle performance. A collaborative project team between Lehigh and Princeton Universities has recently completed an NSF-funded effort to conduct large-scale experiments and validate high-fidelity numerical models. The modeling approaches that were developed during that effort will be leveraged to develop predictive equations that improve upon the existing approaches that are used in current design practice. Performance at both ambient and high temperatures (such as during fire exposure) will be considered. The cost match for this project will be provided by a parallel FHWA-funded effort that focuses on the structural-fire performance of bridges, including those supported by welded steel plate girders.
