Pre-stressing and arrival of more-strength material permit constructions of much lean floors slab with least value with
natural frequency along with damping. Within some circumstance, vibration because of forcing frequency due to normal man
activity can be annoying to occupant. Since the occupant is counted both sources and the sensors, the vibrations can’t be isolated and
should control by the structural systems. In recent time, there are limit knowledge related to the overall dynamic characteristic of
concrete-slab, even including contribution of individual structural along with non-structural component. The programme of modal
testing related to slender one-way spanning with 50 percentage scale post-tensioned concrete slabs are reported. Test is carried out by
utilization of electro-magnetic shakers, instrument hammers, heel-drops, and walking-excitation, to check all floors dynamic
characteristic
