In this paper an equipment and a procedure for the determination of large object inertia parameter are described. The procedure is based on the rigid-body complete motion equation. A least-square optimization is used to identify the 10 inertia parameters starting from the experimental data acquired during both, static and dynamic tests. The equipment, named BTI (in Italian: Banco Tensore d'Inerzia), and the identification procedure have been calibrated using structures made of double T beam elements opportunely assembled in order to realize different standard specimens. The results of the above calibration are presented.
