Abstract: The main body of the Nakaoki Bridge incorporates an oblique bent that had been used during the construction of the Megami Bridge. This is the first time that a bent has been recycled for the purpose of reducing both construction costs and the impact on the environment. A model of this bridge's superstructure was constructed last year to test the bridge's natural vibrations. This model was subjected to microtremors in order to compare the model's natural vibrations with those of the actual bridge. A non-linear seismic response analysis also was carried out to study bridge's earthquake resistance under Level Ⅰand Level Ⅱ earthquake motions.
