WebReinforcing bar, AKA Rebar is used to help concrete stand tension force, although the concrete is strong enough by nature to withstand compression force, it can also crack from load bending tensile force, and therefore it need help resisting the tensile stress using high tensile substance.
WebReinforcing bars that are spaced too far apart could result in relatively large flexural crack widths. Thus, the maximum center-to-center spacing, s, of the deformed longitudinal bars to limit crack widths is given by the following equation (see ACI Table 24.3.2): where f s is the calculated stress in the flexural reinforcement closest to the tension face of the section … Web30 Oct 2024 · Tension capacity in concrete is known to be much weaker than compression capacity and is seldom used without reinforcing steel bars when tension is required. A statement in the ACI 318 Structural Concrete Building Code suggests that for most conditions tension should be taken as zero (ACI Committee 318, 2014).
