Techniques to Control Reduce Floor Vibration | SBC Magazine
· In particular, many home buyers are aware of their floor's "vibration" in response to foot traffic, which some people find annoying or disturbing. In Canada, the building code includes limits on floor vibration. But codes don't regulate floor vibration. So most builders design for deflection only—typically by holding deflection due to live load to a maximum of .

Floor vibrations
Groundborne vibrations can be problematic, but are best dealt with at source, repairing the pothole in the road. However, where problems are anticipated, such as when a building is adjacent to a busy road, steps should be taken to minimise the transmission into and through the building structure. Careful detailing of the structure and foundations plays a key role in this .
