ABSTRACT:
A construction element comprises a wide-flange steel beam having a web-flange thickness ratio of at least 0.8. Anchors or holding members in the form of studs or wire fabric are secured only to the web of the beam, and a reinforcing bar or plate extending along the beam is in turn welded to the achoring members. The area between the flanges of the beam is then filled with a concrete body in which the holding members and reinforcing elements are embedded for fire resistance.
