Since thermal damage of concrete causes the formation of micro-defects according to physicochemical changes, the adoption of a sensitive nondestructive evaluation method is required. This study introduces an nondestructive evaluation method for thermally damaged concrete, which is on the baasis of nonlinear resonance characteristic. The test was investigated to evaluate thermal damage of concrete and to demonstrate the suitability of the proposed method
