Abstract Based on the reinforced concrete box girder continuous pedestrian bridge, through vibration characteristics test and in-depth analysis of its significant vertical and lateral vibration with the finite element theory considering to the structure as a whole, according to the results with field test and calculation. The inadequacy of the existing evaluation methods of pedestrian bridge was provided, the comfort and quality of the bridge were evaluated, and suggestions on how to evaluate the footbridge comfort were put forward. The practical referential value and effects for the design and maintenance of this type of bridge are predicted.
