m=Es/Ec. The modular ratio is not constant for all grades of concrete. It varies with the grade of concrete. Es/Ec is generally not used to calculate modular ratio for reinforced concrete designs. As per IS 456-1978; m is calculated by the following formula m = 280/3σ c bc. where, σ c bc = permissible compressive stress in concrete in bending.
