[0002] A reinforced concrete beam is a beam made of reinforced concrete. Reinforced concrete beams can be constructed as independent beams, integrated with reinforced concrete slabs to form beam-slab floor systems, or integrated with reinforced concrete columns to form single-story or multi-story frames. Reinforced concrete beams come in a variety of forms and are the most basic load-bearing components in building construction, bridge construction, and other engineering structures, with extremely wide applications.
