The vibration characteristics of a composite bridge with constrained layer damping (CLD) were investigated using the wave and finite element method (WFEM), effects material geometrical parameters CLD on reduction in analyzed. Firstly, numerical model for dynamic response steel–concrete WFEM. calculated acceleration under wheel–rail force obtained this was good agreement that conventional field measurements. Second, segment established. equation motion based WFEM solved to determine induced by running trains. Finally, covering area mitigation bridges results show 5–10 dB level steel members full frequency range can be achieved installing CLD. A lower shear modulus viscoelastic core is beneficial low-frequency bridge. However, higher required high-frequency range. more sensitive thickness constraining than layer.
