In Aeroelastic Model tests, an elastic model that simulates the dynamic characteristics of the actual building—such as mass, natural frequency, damping, and vibration modes—is used. This model vibrates in a manner similar to the real structure when subjected to wind. The displacement or acceleration of the vibrating elastic model is measured using non-contact displacement sensors (e.g., laser or optical type) or accelerometers. Structural wind loads for design purposes are then evaluated based on the measured time-series data. Aeroelastic vibration tests allow the assessment of wind-induced responses that consider effects such as mode coupling, additional aerodynamic forces generated by structural motion, and aeroelastic damping.
