The aseismicity of a multi-spans highway bridge designed by Vietnam Specification is evaluated by dynamic response analysis according to Japan Specification. The bridge adopted in this study is located at Hanoi in Vietnam where is classified to a low moderate seismic zone based on the investigation. As to Level 1 earthquake, there is no damage in the bridge, i.e. the seismic performance of the bridge is also secured by Japan Specification. As to Level 2 earthquake, though girder's unseating is not calculated, the bridge pier is predicted to have damage due to the large rotation angle at the plastic hinge and the lack of the shear resistance of the pier.
