Taking the composite steel box girder bridge with the main span of 245 m in Fenghuang Road of Jinan City as the engineering background,the dynamic characteristics of the bridge are analyzed by using the spatial dynamic analysis model of the whole bridge.On this basis,the seismic response spectrum and time-history analysis of the conventional system are conducted.According to the results of checking calculation,the optimal design of vertical and lateral damping system is carried out.The mechanical parameters of the whole bridge damping system are given for reference of related bridges.
