Question

The working stress method of design specifies the value of modular ratio m= , where is the allowable stress in bonding compression in concrete. To what extent does the above value m make any allowance for the creep of concrete?

Answer 1

Modular Ratio is defined as the Ratio between Modulus of Elasticity of Steel and Modulus of Elasticity of Concrete. This is because, a Reinforced Concrete is made up of Both Steel and Concrete. In this case, Steel is a Tension member and Concrete is a Compression Member.
