Dimple Ji (M.Sc.)
Lateral–torsional buckling provisions in structural steel design standards were developed using assumptions about residual stresses consistent with fabrication procedures from decades ago. Due to considerably greater control during modern shop welding operations, a re-examination of these provisions is appropriate for welded bridge girders. Dimple will perform laboratory experiments on large-scale welded wide-flange girders fabricated with modern welding techniques. The results of the research will be used to evaluate whether existing design provisions are adequately conservative for predicting the inelastic lateral–torsional buckling capacity of welded girders. The project is sponsored by Supreme Steel and NSERC.
