Development of a numerical model for the prediction of ground-borne noise and vibration in buildings

Significant vibration in buildings near surface or underground railway tracks or roads is attributed to moving vehicles. Traffic induced vibrations in dense urban environments can cause structural damage in buildings and annoyance to the inhabitants of surrounding buildings in the form of vibrations or re-radiated noise.The vibrations within a building have several effect on the building’s structure. The vibrations can vary in a large range from imperceptible to levels causing structural damage. The limit above which the vibrations damage the structure is not clear. Some authors claim
that traffic induced ground-borne vibrations can not damage the structures and at worst disturb the occupants. Others [Cro65], however, state that the damaging effect of low frequency vibrations is cumulative and causes the uneven soil settlement under buildings over a long
time period.
