Further Analysis of Non-Gaussian Wind Pressure Peak Factor Calculation
Table 4
Comparison of frequency-domain characteristics of fluctuating wind pressure in typical regions.
| Region | Vortex scale | Frequency of energy concentration | Energy | Fluctuating wind pressure | Reduction frequency corresponding to energy peak |
| Front edge of separation zone | Large-scale vortex | Low frequency | The energy is high | Large amplitude fluctuation | About 0.1 |
| Reattachment zone | Small-scale vortex | High frequency | The energy is low | Stable pulsation | Near 1 | Wake area | Near 1 |
| The area between the separation point and the reattachment point | Coexistence of large-scale and small-scale vortexes | Intermediate band | The energy is mainly concentrated in two main frequencies, showing two peaks | Intermediate amplitude pulsation | The corresponding reduction frequencies are around 0.1 and 1, respectively |
