Steel Rolled Beam Cambering

Steel Rolled Beam Cambering

Steel Rolled Beam Cambering

(OP)
Hi All,

Usually in our bridge plans we acount for steel weight deflection, slab deflection, superimposed deflection, vertical profile and superelevation effects for the camber diagrams.

Why is the need to show the superelevation effects for camber purposes since camber is only to bring out the deflections from the dead load?

Can anyone shed some light on this?

Thanks,
te

RE: Steel Rolled Beam Cambering

Camber is not only for DL deflections. It is also done to make steel girder bridges conform to the profile. Imagine a simple span bridge with a vertical curve high point halfway across the bridge. Cambering could be done to achieve that shape. Superelevation could also impact camber if there is a transition within the bridge limits.
