WebA Review of Strand Development Length for Pretensioned Concrete ... - PCI WebCDC debonding is particularly important in RC beams with stirrups, as they are prone to debond before the shear capacity of the beam is attained. In this paper it is shown that the CDC debonding resistance of a plated RC beam is analogous to the shear resistance of a prestressed beam; a design procedure based on the shear resistance of prestressed …
