When the modulus of elasticity of the precast and insitu cast concrete are different the flexural rigidity is worked out by? Correct Answer Second moment of area

When the modulus of elasticity of the precast and insitu cast concrete are different the flexural rigidity is worked out by computing the equivalent second moment of area of the composite sections using the modular ratio and the deflections computed under service loads should not exceed the limiting values prescribed in the codes.
