Flexural Strength of Reinforced and Prestressed Concrete

Fig. 1 shows a schematic of the condition of the T-beam at nominal exural strength. Since LRFD requires that the beam be treated as a T-beam once c exceeds hf, the depth of the equivalent rectangular compressive stress block in the ange overhangs is limited to 1hf.

Share Tensile Strength of Steel vs Yield Strength of Steel Nov 25, 2020 · Tensile strength is the resistance of steel to breaking under tensile tension. Its used to specify the point when steel goes from elastic (temporary) to plastic (permanent) deformation. Usually, its measured in units of force per cross-sectional area. Once a piece of steel is pulled past its tensile stress point, it will split apart.
