A measurement campaign for railway-induced vibrations in a building

In October 2016, an extensive field measurement campaign was conducted at a site in Belgium where a threestorey building with a basement is located 33m from a railway line that is used by both freight and passenger trains. Over a period of eleven days, the dynamic response in the free field and the building was measured simultaneously, resulting in a database of over 500 train passages. Nine measurement locations were used in the free field, and sixteen measurement locations were spread across the four floors of the building. In a second set of measurements, transfer functions were obtained using excitations from an impact hammer at a series of 17 sleeper locations over a total distance of 196 m. The vibration levels within the building are, on the whole, smaller than those measured directly outside the building. There is no clear trend of attenuation with floor height, and although it would generally be expected that mid-span locations would have higher vibration levels than nearcolumn locations, this study shows that this is not always the case.
