There are several reasons to control deflection. A concrete floor should have adequate stiffness to prevent changes in deflection that would damage attached partitions or other construction elements likely to be damaged by large deflections. The deflection of a floor should not be noticeable by occupants such as to convey a sense of inadequacy or safety concerns. Since, in some instances, deflection is used as a measure leading of undesirable vibration in a floor, its value must be controlled.
