Abstract (en)

[origin: US4616464A] A composite structural element comprises a steel structural shape whose web is provided with one or more steel plates secured thereto by welding or bolting and embedded in the concrete filling the channels between its flanges. The concrete may also include a reinforcement secured to the plate. With a relatively simple structure the system has increased load-carrying capacity even under fire conditions.
