- Abstract
- One of the modern cities environment issues is noise and vibration created by train traffic, especially since cities today strive towards being more dense. Urbanization leads to new areas built with pre existing railway tracks. This puts a lot of pressure on the structures built on those areas regarding vibrations. Heavy concrete buildings are more resilient against vibrations than light-weight structures, that are becoming more and more popular. More knowledge is needed to create buildings that is resistant towards vibrations and noise.
The main objective in this report is first of, to get a better understanding of how vibration impact the inhabitants of structures.

Urbanization leads to new areas built with pre existing railway tracks. This puts a lot of pressure on the structures built on those areas regarding vibrations. Heavy concrete buildings are more resilient against vibrations than light-weight structures, that are becoming more and more popular. More knowledge is needed to create buildings that is resistant towards vibrations and noise.
The main objective in this report is first of, to get a better understanding of how vibration impact the inhabitants of structures. This through evaluating a building in Helsingborgs Campus which is known to be exposed to vibration caused by trains. The evaluation is executed by doing measurements using seismometer and sonometers placed on different positions in the vicinity of the building. The seismometers used are omni-directional where the train direction are named north, second horizontal direction named east and lastly the normal direction, named normal. The measurements were executed simultaneously to properly be able to evaluate the data.
The evaluation of the result shows that the type of train definitely has an impact on the vibration levels. Also the speed is of great importance, although it does not impact the normal direction for unknown reasons. The highest amplitudes measured is always in the normal direction within the building which is a expected result due the measurements are executed on floors. The result in every measurement position follows the same pattern where the highest amplitude is the in normal direction, followed by the east and lastly the north direction not counting the measurement position close to the facade. This mat be due to stabilization from the concrete wall. (Less) - Popular Abstract (Swedish)
- Buller är erkänt som det näst största miljörelaterade hälsoproblemet enligt WHO \cite{WHO} och det är därför är det viktigt att skapa goda metoder för att undersöka hur fastigheter påverkas av buller och vibrationer. Detta examensarebete har fokuserat på att undersöka buller och vibrationer i en flervåningsbyggnad orsakat av tågtrafik.
