الوصف:	In this study, ERA was applied to investigate the estimation accuracy of dynamic characteristics of the structures which have close eigenvalues. Series of numerical analysis to estimate structural frequency and modal damping were conducted for a two-dof model using the simulated external forces induced by impulse force and white noise. The estimation results obtained by these simulations demonstrated good agreement with assumed values. Next, the method was applied to the vibration data induced by human impact excitation for three existing stress ribbon bridges. The results showed that the method can estimate the dynamic characteristics accurately for the structures which have close eigenvalues.
