ABSTRACT
The inescapable conclusion from our review of experimental information on bond is that the distribution of bond stress along a reinforcing bar and its maximum value depend on complex interactions of many variables, such as bar prole, concrete strength, cover thickness, cracking, and connement. Accuracy in predicting the magnitude and distribution of bond stress in an actual structure is not to be expected. The object of design calculations for bond is not prediction. It is to proportion a safe and serviceable structure. Procedures used for determining adequacy of bond are better understood and used in that light.
