Recently, deterioration of infrastructures has become obvious as social problem, and application of structural health monitoring to maintenance attracts attention increasingly. However, method to evaluate the relation between local damage and data measured by monitoring has not been investigated enough. Then, damage detection method focusing on the spatial deformation has been proposed and is investigated by numerical simulation continuously. In this paper, damage evaluation of RC beam is conducted in combination of experimental and analytical approach. In experiment, latest optical distributed strain measurement system is applied. And damage detection method using wavelet decomposition is also proposed and evaluated.
