Comparison and analysis of dynamic performance of straight bridge and curved bridge

Aiming at the dynamic performances of the straight bridge and curved bridge,the author establishes the space model especially on the straight bridge,continuous curved bridge and pier beam consolidation curved bridge based on adopting large scale common finite element software ANSYS,and gets model vibration and frequency analysis on it,describes the differences of the dynamic performances between the straight and curved bridge,points out that the integrity of the curved bridge worse than straight bridge's.
