Abstract
A fracture mechanics approach to crack control design of reinforced concrete beams in flexure (Mode I) is proposed. The model yields the minimum area of tension steel required of a concrete beam of rectangular cross-section to safely sustain a design moment within the prescribed limit of permissible crack height. An iterative procedure is developed by satisfying simultaneously the fracture criterion of crack growth and the equilibrium condition at incipient fracture.
