An experimental model was made from two materials - wood and plasterboard. Supports could be alternatively considered, but the simply supported beam was considered in this research. Modal analysis was performed from recorded data (18 accelerometers along the experimental bridge in vertical direction and six sensors in horizontal directions). Two artificial exciters were used for harmonic excitation. The placement was asymmetrical. Dynamic characteristics as natural frequency, damping ratio and corresponding mode-shape were obtained using two methods (Discrete-Time Fourier Transform and stabilization charts using the Stochastic Subspace Identification method). Comparison of the methods was prepared. Some mode-shapes were processed for identification of the damage by application FE model updating method.
