Random Vibrations - CEE 358/458

Random Vibrations

Newly developed course. Offered in Spring 2014 (as CEE 497), 2015 (as CEE 497), 2016, 2017.

  • Brief review of probability theory, with focus on the aspects used throughout the course.
  • Theory of random functions: definition and description of random processes; autocorrelation function and spectral density; ergodic theorem; differentiation and integration of random processes.
  • Important models of random processes, with focus on the description of natural loads in structural engineering (seismic ground motion, wind fluctuations, ocean waves).
