This Technical Guidance Note is an introduction to the assessment of floor vibrations. Since the advent of lighter structures that have longer spanning elements within them, the built in dampening effect buildings have had historically has become less pronounced. Despite this, floor vibration can be an overlooked criterion during the design process. This can lead to expensive remedial works being carried out on structures after they have been built, as occupants complain of discomfort due to excessive movements and vibrations.
