| Abstract: | Based on the finite element software,ANSYS,the spatial model of a long span X-style box-section arch bridge was created.With the consideration of warping and shear deflection effect,the dynamic properties of the bridge were analyzed by the Block-Lanczos method and the data of frequencies and shapes were obtained.At last,the dynamic properties were assessed and some conclusions were obtained which can be a reference to the bridges with same style. |
