A Research on Diagonal Crack Width Formula of RC Beam
Based on the shear performance of existing reinforced concrete beam oblique section and referring to the slipping theory of bending crack of the beam, a formula of the diagonal crack width is proposed through the equilibrium condition, the geometric condition and the concrete failure criteria. This formula has explicitly and clearly the physical concept.So,it can be used to check the maximum diagonal crack width of RC beam in the design.
