This report describes a study which investigated the technical feasibility of using a modal parameter based technique, also known as the Damage Index Method, to quantitatively evaluate welded reinforcement splices during the construction process. This method of non-destructive damage evaluation, was able to detect flaws in a reinforcement bar as small as 1/32 inch in depth. It was also shown that good agreement exists between the predicted strengths of the welds and the strength that was measured in the laboratory.
