| Abstract: | Based on Finite Element Method（ FEM）, the common software MIDAS/Civil has been used in seismic calculation of Simple beam bridge with pre - stressed hollow slab. 3 - D FEM is used to do dynamics simulation for simple beam bridge with pre -stressed hollow slab, under the earthquake action of El and E2, the seismic property such as anti - bending, anti - shear capacity of the key sections, the bearing thickness and bending stability have been analyzed, the practical seismic measures have been proposed. Therefore, the necessary theoretical guidance and technical support will be provided for quality control of the bridge construction. |
