For a calculation I activated the option "detailed calculation". Are the bearing loads already specified with the reduced vibration coefficient for dimensioning the substructure?


The support forces will be combined in the same way as the internal forces from the load cases with consideration fo the dynamic coefficients. For this purpose, the bearing forces (except for LF1 and LF2) are multiplied by the ratio of vibration coefficient carrier to vibration coefficient bearing and added according to the LK criterion, since the wheel loads from LF3 already include the vibration coefficient for the carrier.

With the option only max / min, only the extreme values of the bearing forces for the corresponding
Directions issued, ie the characteristic bearing forces multiplied by the associated
Vibration coefficient for supports (see Figure 5.6).

There is already an interesting webinar on the subject " Dimensioning of crane runways according to Eurocode 3 " on our homepage.
