Abstract
We propose operational transfer path analysis for structure subjected to floor vibration and experimentally examine a vibration transfer path from the floor.The analysis needs a kind of excitation distribution for the structure but it is very difficult to prepare the many exciters on the structure.For that purpose,an additional mass is set up on the structure because it is easy to use inertia force of the additional mass as excitation force.The example where the additional mass is applied to a double floor structure is demonstrated.
