Erschütterungen im Bauwesen: Messergebnisse an verschiedenen Gebäuden

The subject of the vibration transfer into buildings is studied experimentally and theoretically. Small buildings excited by pile driving induced vibration show a structure-soil frequency lower than f = 10 Hz but with only little amplification compared to the soil. The amplitudes of the foundation and the wall are reduced at higher frequencies, the strongest reduction V = 0,1 was found in a multi-storey building excited by underground traffic. On the other hand, the highest amplifications V = 10 are found at the floor resonances. In a subsequent article a simple theory is presented which combines the longitudinal vibrations of the walls and the transversal vibrations of the floors with the compliance of the underlying soil. Realistic amplifications of the floor are achieved as a result of the compliance and the radiation damping of the soil.
