Understanding Stresses and Modular ratio RCC Structures

Sep 08, 2012 · 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: 4561978 m is calculated by the following formula: m = 280/3σ c bc. where, σ c bc = permissible compressive stress in concrete in bending.
