Title: Mechanics of Bond and Slip of Deformed Bars in Concrete
Author(s): LeRoy A. Lutz and Peter Gergely
Publication: Journal Proceedings

Abstract:The action of bonding forces, and the associated slip and cracking are examined for bars with various surface properties. The mechanics of slip of deformed bars in concrete is discussed, with the support of experimental data. The stresses and deformations in the concrete, caused by the bonding forces, are presented. The ACI Building Code shear stress requirements are studied in terms of the corresponding limiting bond stresses.
