This paper presents a fundamental study of structural damage identification using displacement and vibration measurement results. The natural frequencies and deflections of beams were measured using a Laser Doppler Velocimeter (LDV), and the effects of damage on the natural frequencies and deflections were investigated. The effect of damage on the deflection time response of beams subjected to moving loads was studied using the finite element method, and it was shown that the presence and location of damage can be identified by determining the rate of change in the deflection time response of undamaged and damaged beams.
