Moment Capacity Of Concrete Beam Calculator

15.06.· A concrete beam is designed to resist forces like shear, moment, torsion etc. which satisfies the limit state of collapse. The moment carrying capacity of the beam is determination of maximum safe allowable moment that a beam can carry. It is the resisting moment produced by the compression stress block or tension stress block about the neutral axis. This moment capacity of concrete beam
