Abstract:

This Coastal and Hydraulics Engineering Technical Note CHETN describes theoretical work supporting the development of a nondestructive evaluation NDE technology that can quantitatively measure tension in structural steel reinforcing members. In large concrete structures such as locks and dams, the corrosion of tensioned steel components can lead to loss of tension and consequent severe problems such as cracking of the concrete or fracturing of the steel. The theory and application address the problem of determining tension in concrete-embedded pre- and post-tensioned steel reinforcement rods.
