In the HFFB test, lightweight and high-stiffness rigid models are employed. The wind forces acting on the model—including forces and moments along each structural axis—are measured using a six-component force balance. Based on the time series data of the measured wind forces, wind force coefficients are calculated. These coefficients are then used in spectral modal analysis to evaluate wind-induced responses, including both mean and fluctuating components.

▣ Mean and Fluctuating Wind Force Coefficients​
▣ Base sheer, base overturning moment, and torsional moment
▣ Combined static floor-by-floor wind load
▣ Lateral displacement
▣ Wind-induced acceleration, evaluate serviceability (AIJ, ISO, NBC)
▣ Basic design of vibration control device (TMD, AMD, TLCD, etc.)
