Abstract: In this paper, a field experiment was carried out to
study train-induced environmental vibrations. During the
field experiment, velocity responses were measured at different
locations of a six-story masonry structure near the Beijing- Guangzhou
Railway and along a small road adjacent to the building. The results
show that the velocity response levels of the environmental ground and
the building floors increase with train speed, and attenuate with the
distance to the railway track. Heavier freight trains induce greater
vibrations than lighter passenger trains. In the multi-story building,
the lateral velocity levels increase monotonically with floor elevation,
while the vertical ones increase with floor elevation in a fluctuating
manner. The indoor floor vibrations are much lower than the outdoor
ground vibrations. The lateral vibration of the building along the
direction of weak structural stiffness is greater than along the
direction with stronger stiffness. A larger room produces greater floor
vibrations than the staircase at the same elevation, and the vibration
at the center of a room is greater than at its corner. The vibrations of
the building were compared with the Federal Transportation Railroad
Administration (FTA) criteria for acceptable ground-borne vibrations
expressed in terms of rms velocity levels in decibels. The results show
that the train-induced building vibrations are serious, and some exceed
the allowance given in relevant criterion.
