Structural Vibration and Ways to Avoid It |

Structural Vibration and Ways to Avoid It (Platforms, FPSOs) Dynamic loadings take many forms. Two parameters can characterize such loadings: Their magnitude and their frequency content. Dynamic loadings can be replaced by static loadings when their frequency content is low compared to the natural frequency of the structure on which they are applied. Some people will refer as quasi-static
