The construction of lighter and longer floor structures in recent years has resulted in an increasing incidence of floor vibration. Modern floors which are frequently reported to have annoying vibration are thin lightweight concrete slabs supported by open web steel joists.
Cement contractors place these expansion joints in the floor to allow for the shrinkage that occurs in the concrete slabs as they cure. The magnitude of the motion. The joints are also helpful if the slabs experience major temperature changes.
Much vibration theory is derived from experience with steel and wood floors. Acceptance criteria for sensitive equipment.
