When an extreme earthquake occurs, roads and bridges are fundamental infrastructures to evacuate the affected people and to transport the emergency equipment and materials. For these emergency activities, it is essential to detect immediately after the earthquake the severe structural damage that affects the performance of structures. This paper proposes a method for quick earthquake damage detection/evaluation of reinforced concrete bridge columns, which has been developed through investigations of dynamic response properties of reinforced concrete bridge columns obtained from shake table tests. An intelligent sensor unit was developed that captures changes of response period of a bridge column. Field measurements of traffic induced vibrations of bridges were also conduced to evaluate the efficiency and to improve the applicability of the proposed method.
