A theory of transfer bond resistance of deformed reinforcing bars in concrete under lateral pressure

Synopsis The basic bond mechanism for reinforcing bars in concrete under external pressure is considered and an existing partly cracked elastic theory for bond resistance is extended to cover both uniform and non-uniform distributions of external pressure. Results obtained from this theory are compared with experimental results at various stages of bond failure. The prediction of pull-out force at 0·1 mm free-end slip is found to be satisfactory.
