Long-Term Operational Modal Analysis

The Goodwin Hall Smart Building uses 200+ accelerometers and Operational Modal Analysis to track modal parameters over the life of the building. The objectives of this research are:

  1. Refine methods for automated moda analysis
  2. Understand the impact of environmental parameters (wind, temperature, occupancy) on the response of the structure.

We have developed a public, open-source MATLAB library for Operational Modal Analysis. Access it here.
