Cambering Steel Beams - AISC
from the top of the concrete slab. b. Don't cold-camber beams to which a cover plate will subsequently be welded. The heat thus generated at one flange will generally be enough to significantly alter the camber curve. c. When cold-cambering by force, make sure that there is sufficient length of bearing at the load points in order to
