| 520 | _aMode shapes are the predominant dynamic sensitive features for structural damage identification. This paper proposes a vibration-based bridge global damage identification technique using mode shape data. Two cases of global damages: increased boundary stiffness as a result of scouring are analyzed by the proposed vibration-based damage diagnostic technique. New damage indicators based on the shape change of the first mode shape gradient and root mean square difference of first mode shape between healthy and damaged bridge are proposed for bridge bearing and scouring damage identification. | ||
