Cambering: Cold Versus Heat for Steel Bridge Beams
Steel beams used for bridge and highway structures are frequently curved to accommodate the design of a structure. This can be accomplished by cambering or sweeping. Cambering is the curving of a beam about the strong axis of the member, while, sweep applies to the curving of a member about the weaker axis. Cambering is typically performed by a steel fabricator after the member has been cut to length and punched or drilled. Beams that require square or parallel ends must be cut after cambering. Cambering steel in fabrication shops is usually achieved by applying a force on a steel member by mechanical means (Cold Bending) or applying truncated heat (Hot Bending). When camber is required in plate girders, the fabricator will typically cut the web plate to the desired camber profile prior to welding the flanges. Cold cambering is the most common method used in fabrication shops to induce camber in a steel member, as it is a simpler and more cost-effective method than heat cambering.
