Civil structures play important roles in human being's life for convenience and practical purposes. But in the same manner, it needs proper maintenance because of the change of nature such as earthquake, typhoon, flood and the degradation of themselves with passing of time. Therefore, it has emphasized necessity of health monitoring system that always measures degree of deterioration of civil structure and predicts the life span of the structure and informs its repair time. Besides the existing strain gauge, potential candidates of the sensing elements of the system are optical fiber sensors because of no disturbance from electromagnetic waves, good durability, quick response. In this experiment, embedded intrinsic Fabry-Peort optical fiber sensors were employed.
