Abstract: The Inverse Pseudo Excitation Method is utilized to identify the loadings for a structure subjected to random excitations. The method was successfully applied to the loading identification of two structures with different damping ratios: a uniform steel cantilever beam and a plastic glass cantilever beam. Advantages of this method include its computationally efficient nature, and its ability to reduce the ill-conditioning of frequency response function near some resonant frequencies because the singular value decomposition is adopted. Frequency response functions and coherence coefficients were used as criteria in the adjustment of the setting status of the drive rods. The identified loadings agreed with the actual values perfectly well. It is shown that the Inverse Pseudo Excitation Method is promising in engineering applications.
