WebTesting of many reinforced concrete beams has shown that the average stress within the compressive zone is 0.85β 1 fc ', and the resultant location is β 1 c /2 from the face of the concrete beam, as shown in Figure 5.23a. The coefficient β 1 ranges from 0.85 for fc ' ≤ 4000 psi, to 0.65 for fc ' ≥ 8000 psi (Figure 5.24). Web7.3mm. This video shows how a reinforced concrete beam fails when too much longitudinal (or flexural) reinforcement is provided. Longitudinal steel bars are provided to resist the tensile forces in the bottom of the beam due to bending (or flexure). Shear reinforcement (links) have also been provided to ensure that the beam doesn’t experience ...

WebMar 21, 2024 · Failure modes in reinforced concrete beams are classified into two major types: flexural failure and shear failure. The former occurs when the imposed load exceeds the flexural capacity of the materials of the beam, while the latter occurs due to deficiency in shear resistance between different materials of the beam.
