Reinforcement in concrete

A beam bends under bending moment, resulting in a small curvature. At the outer face (tensile face) of the curvature the concrete experiences tensile stress, while at the inner face (compressive face) it experiences compressive stress. A singly reinforced beam is one in which the concrete element is only reinforce… WebApr 12, 2024 · The MarketWatch News Department was not involved in the creation of this content.
