Discussion: beam under bending

Consider a beam section under bending with M_u=206 kNm. Let f_{ck}=25MPa; f_{yk}=500MPa. Per EC2, i can find the reinforcement area about A_s=1012mm^2 .

 

 

But if this section with A_s=1012mm^2 under this M_u=206 kNm, the question is simple, what will be the axial strain \epsilon of the section? \epsilon_c=?; \epsilon_s=?.
