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.
