Multi-support excitation analysis for an existing suspension bridge (Ohnaruto Bridge) was carried out applying the actually recorded accelerations of Hyogoken-nanbu earthquake (1995) on each foundation. The analyzed results were compared with the actually recorded response of the superstructure, and the analyzed results of uniform excitation analysis. The results of multi-support excitation analysis reproduced the better approximation for the first vertical bending mode deformation than the results of uniform excitation analysis.
