4- Moment of Inertia of Cracked Section Transformed to Concrete

5-Quadratic eq

6- Equivalent Stiffness , Is =Ic/n
for axial force, εc = εc  fc/Ec = fs/Es  ==> F/(Ac Ec) = F/(As Es) ==> thus As Es = Ac Ec  ==> As = Ac * Ec/Es = Ac /n                                      
and for moment, εc = εc  fc/Ec = fs/Es  ==>  M*y/(Is Es) = M*y/(Ic Ec) == > Is = Ic Ec/Es = Ic/n
