| Abstract: | Techniques of modal tests and dynamic modification are applied to the analysis of large cylindrical wharf structures. Modal frequencies and vibration modes are drawn from modal tests of a large cylindrical wharf model under 4 constraint boundaries. Furthermore, the optimum position and level for mass and stiffness modification are obtained. The results provide a scientific basis for aseismic design of large cylindrical wharf structures. |

| Keywords: | wharf large cylindrical structure dynamic characteristics modal tests dynamic modification |
