What is the modular ratio of m20?
The modular ratio is the ratio of the modulus of elasticity of steel to the modulus of elasticity of concrete. For M20 concrete, which typically has a characteristic compressive strength of 20 MPa, the modulus of elasticity is generally assumed to be around 25 GPa. If we consider the modulus of elasticity of steel to be approximately 200 GPa, the modular ratio (n) can be calculated as n = E_steel / E_concrete, resulting in a modular ratio of about 8. This means that the stiffness of steel is roughly eight times that of M20 concrete.
