abstract = {{The designs of various girder support systems were reviewed recently in a MEDSI School tutorial*. A comparison of their horizontal transmissibility values in (2-100) Hz band showed that the NSLS-II girder support system had a lower horizontal transmissibility despite its first natural frequency being the lowest (~30 Hz). Detailed vibration tests and FE analyses have been performed to understand this anomaly and to assess the role of viscoelastic damping pads underneath the NSLS-II girders. The analyses were extended to include harmonic response to model viscoelastic properties and random vibrations to obtain relative motions between the magnets. The results of these new tests and FE analyses are discussed in this paper.}},
