Summary

The vertical eigenfrequencies and mode shapes of a single-span suspension bridge are computed using the method by Luco et Turmo [1]. For the sake of completeness, the computed modal parameters are compared with those obtained using the method by Sigbjørnsson & Hjorth-Hansen [2] and Strømmen [3].

Content

The submission contains:

  • eigenBridge.m: It computes the modal parameters of a suspension bridge [2,3].
  • eigenridge2.m: It computes the vertical modal parameters of a suspension bridge, following Luco & Turmo [1].
  • eigBridge_Verification.m: Function used for the verification procedure.
  • Verifications.mlx : reproduction of some of the results by Luco & Turmo [1].
  • Application.mlx: Compare the numerical implementation of eigenBridge2.m against eigenBridge.m
