Abstract

The large amount of data from air-coupled impact-echo tests from bridge decks must be manipulated and presented such that infrastructure engineers can effectively visualize the condition of the structure. To address this problem, we present the data in the form of "4-dimensional" images, which indicate the location of concrete delamination defects using air-coupled impact-echo data. The basis of the 4-D plot is introduced, and the effects of image parameter variation, such as frequency range and transparency index, are studied and experimentally confirmed.
