| 摘要： | The pieis' deformations on elastic foundation include the elastic deformation caused by force and the deformations derived from the foundation's rotation and translation. On the basis of that, the mode shape function of the piers is put forward, and the function of super structure is adopted by means of Hermite polynomial, then the whole seismic vibration equation of continuous beam is given on by Lagrange Equation , thus the structure's frequency and in fluencing coefficient of its vibration mode can be calculated which involve the foundation' s complex parameters. Finally,the experiment using impact excitation method is carried out in doors. The modal parameters of which have matched the theoretic ones by modal analysis. The method presented and experiment results could give reference to seismic assessment of existing continuous beam bridges. |
