Measured Responses of a Corrugated Steel Ellipse Culvert at Different Cover Depths

Typical design and installation methods for corrugated steel culverts involve consideration of a minimum burial depth and most current North American design codes consider failure only due to excessive circumferential force in the conduit walls (i.e., hoop thrust). However, recent studies have shown that the bending moment is often the more dominant behavior for corrugated steel culverts at shallow cover. To address this issue, an elliptical...
