摘要

In this paper, a method to evaluate the crack size of concrete structures by infrared thermography was investigated. This method is based on the relation between the crack depth or width and thermal distribution in concrete. First, the influence of crack depth and width to thermal distribution was examined. Next, the influence of the distance between cracks and heater to thermal distribution was investgated. The effectiveness of this method was confirmed by the results of the experiment on flexural cracks in reinforced concrete beams. From these results, it was demonstrated that the thermal distribution measured at the surface of concrete by infrared thermography was effective in evaluating the crack size in concrete structures.
