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 is identical to File ID: #51815) and is inspired from [5,6]
  • eigenridge2.m based on works of [4]. I am simply writing the equations and their solutions in a numerical way.
  • eigBridge_Verification.m: its only purpose is to verify the numerical implementation of eigenBridge2.m
  • Verifications.mlx : It is a verification of the works of [4], where I try to obtain exactly what [4] show in their paper.
  • Application.mlx: I compare eigenBridge.m with eigenBridge2.m

Any comment or idea of improvement is warmly welcome.
