Steel-Web Bridges Show Superior Dynamic Response Over Concrete-Web Bridges
The study compared the dynamic response of two types of box girder bridges' deck pavement: one with corrugated steel webs and one with concrete webs. Using computer simulations, researchers found that the bridge with corrugated steel webs had greater dynamic response than the concrete web bridge. The steel web bridge is lighter, better at handling earthquakes and bending, and controls deflection better. The concrete web bridge, on the other hand, is stronger in shear and torsion. The response of both bridges' deck pavement to dynamic loads was more pronounced than to static loads.
