First, a technique for identifying damage to structures is proposed which uses harmonic excitation force generated by a micro shaking device. Fourier response functions (FRFs) obtained by dividing the Fourier amplitudes of acceleration responses by the amplitude of the harmonic excitation are used to identify damage. Secondly, vibration testing on a steel truss bridge was conducted to investigate the effectiveness of the proposed technique as well as the use of a micro shaking device. Damage models of the steel truss bridge were created by cutting sections of bracing members. Finally, identification of damage using the proposed damage identification technique was conducted and its validity was examined.
