Load identification is useful for structural health monitoring. Predecessors proposed one load identification method, and confirmed by simulation that this method is applicable to real structure. We need to confirm the applicability to real structure by experiment too. So , we focus on wind tunnel experiment, and tried to measure strain and deformation distribution on wind tunnel experiment. We measured strain by FBG (one of optical fiber strain sensors), and estimated deformation by using beam theory. And by experiment and simulation of simply supported beam subjected to bending loads, we confirmed that load can be identified by using strain and deformation information with almost the same accuracy and stability.
