Calculation of First Natural Frequency in RF-/TOWER Loading

Which formula is used in the RF‑/TOWER Loading add-on module to calculate the first natural frequency for the determination of the structure coefficient?


Answer:

The first natural frequency is required to determine the structure coefficient. It is determined using not a generalized formula, but the integrated eigenvalue solver RF‑/DYNAM, taking into account the real mass distribution and displaying the results in Column A of Table 2.3.
