RAM Steel does the vibration check based on FloorVibe. However, with complex geometry finite element basis on design guide 11 is required to check vibrations. Other programs like ETABS, Robot Autodesk or Tekla does these calculations. Please have this feature in RAM Elements as soon as possible.
I do use Elements currently to get my natural frequencies for vibration checks of stairs, but am looking at purchasing the Modal Analysis and Time History Analysis add-ons for Dlubal RFEM (at significant cost, unfortunately) to be able to go beyond that. So that would be really nice to be able to get footfall response values from Elements.
