The performance of Japanese high-speed railway bridges regarding train-induced deck acceleration specified in Eurocode, which is different from Japan, has not been sufficiently verified. This study conducts acceleration measurement of a slab track type PC box girder bridge in Japanese high-speed railway. The global and deck local modal characteristics are identified, and the maximum deck acceleration specified in the Eurocode is evaluated. As a result, the maximum deck acceleration of the bridge is much lower than the Eurocode limit value despite the resonance condition. Unlike previous reports for European bridges, the main deck vibration modes of the bridge are over 40 Hz, thus the deck local vibration did not affect the evaluation of deck acceleration.
