| Abstract: | Over-head pier bulk wharf is a new structure and applicable in The Three Gorges reservoir district. Taking the large-size bulk export wharf for environmental protection of steelworks of Chongqing as an example, the 3D finite element model for the structure was built by finite element method and then a modal analysis on it was given. After the mode at each stage was obtained, the key mode was extracted to analyze the characteristics of the vibration shape. At last, the self-vibration security estimation was given under the basic work condition of the wharf. |
