With the RF-/TIMBER Pro add-on module, it is possible to perform the vibration design known from DIN 1052 for the design according to EN 1995-1-1. In this design, the deflection under permanent and quasi-permanent action at the ideal one‑span beam may not exceed a limit value (6 mm according to DIN 1052). If the relation between the natural frequency and deflection is considered for a hinged one‑span beam that is subjected to a constant uniform load, then the 6 mm result in a minimum natural frequency of about 7.2 Hz.
