WebOver Reinforced Section The steel provided in the beam is such that concrete reach the limiting values of strain prior to steel. This results in breaking of concrete and since now there is no concrete present to take the compression the beam fails suddenly. WebFailure 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.
