| Abstract: | The method for restrained mode synthesis applied in the dynamic analysis of prefabricated bridges is presented in this paper,so that the low frequencies and the intrinsic modes of prefabricated bridges can be calculated. The structural features and substructural mode information of the bridges are also discussed. The calculating formulas are induced from common theories,and the errors are pointed out. The example put forward here demonstrates the rationality and validity of the method. |
