DETECTING CRACKS IN THE BEAMS AND COLUMNS OF A POST-TENSIONED PARKING GARAGE STRUCTURE USING THE IMPACT-ECHO METHOD

This paper presents both a brief explanation of the impact response of bar-like structures and an application involving the use of the impact-echo method for detecting cracks in the beams and columns of a post-tensioned parking garage structure. The information gained from the impact-echo tests was used to aid in specifying repair measures for the structure. In the process of implementing repair measures, selected impact-echo results were verified.
