Mode shape superposition method
Web15 mrt. 2024 · Solving linear structural dynamics problems using mode superposition is a very efficient technique. When using mode superposition together with damping, there are certain things to note. The initial eigenfrequency analysis should be performed using the undamped problem, and the damping is then included only during the mode … Web9 apr. 2024 · The geometric nonlinearity of the structural static deformation affects both the mode frequencies and mode shapes. And the mode shapes cannot be approximated by harmonic functions. When the static deformation is significant, the structure’s local RMS response is substantially affected.
