Question

How does the assumption of ''plane sections remain plane" simplify the calculation of the maximum possible depth of the neutral axis,x? By making an appropriate drawing, calculate the maximum possible value of x for a reinforced concrete section which has concrete class <= C50/60 and steel S500. Explain why EC2 apply this limitation (i.e., x<=0.45d).
