Vibration measurements of a steel joist floor system

Abstract [en]

A steel joist floor, prefabricated in sections, is investigated with respect of vibration levels. Measurements are performed using one, two and four elements joined together. Different modifications to the floor are tested to see in what way they affect the vibrations. An extra damper has a considerable effect, especially to a certain kind of mode shapes. Introducing lumped supports at the long-sides give further improvement. Changing the direction of the floor gypsum boards give a minor effect.
