- Abstract
Based on the wave transfer matrix method, wave localization in a disordered periodic viaduct undergoing in plane vibration is investigated according to the Wolf’s algorithm in this paper. With the proposed model, the influences of the pier-height and beam-length disorders on the wave localization are examined. Also, the interactive effect of the damping and disorders on the wave localization in the disordered periodic viaduct is studied. Numerical results show that: in the pass-bands, for the assumed parameters of the viaduct, the localization due to the damping is larger than that due to the disorder. While in the stop-band, the viscosity of the materials tends to increase the Lyapunov exponent,while the disorder tends to diminish the Lyapunov exponent.
