n0 is the natural frequency of the unloaded bridge in [Hz] L^ is the determinant length in [m] a is a coefficient for speed

(4)P The calculation shall be made for upper and lower limiting values of n0, unless it is being made for a particular bridge of known frequency. The upper limit of n„ is given by:

and the lower limit is given by:
