| Abstract: | Dynamic behavior of Shangyou River Bridge, a simple supported-to-continuous girder bridge, is analyzed by means of spatial beam segment finite element method. Limited acceleration transducers are placed on the deck, and the vibratory signals are sampled periodically under environmental exciting. The vibratory mode of the practical bridge is tested and analyzed. The results indicate that the calculation mode by the spatial model is very close to that measured in site. |
