We carried out operational transfer path analysis using addisional mass for a structure subjected to floor vibration to identify a transfer path from the floor to an evaluation point via a support. The contribution of transfer path between the evaluation point and three supports was respectively investigated and the support with largest contribution was identified. We could reduce peek amplitude of evaluation point by anti-vibrational measure where a spring constant of the identified support was made small. Effectiveness of the operational transfer path analysis using additional mass was demonstrated.
