Vibration of an Offshore Structure Having the Form of a Hollow Column Partially Filled with Multiple Fluids and Immersed in Water
Figure 3
The lowest four mode shapes of the hollow beam are shown in Figures 3(a)–3(c), respectively, where (a), (b), and (c) refer to the 1st, 2nd, and 3rd mode shapes of the hollow beam. Besides, the curves − − − −, — — — —, – – – –, …………, and denote the mode shapes of the hollow beam filled with the upper fluid height , respectively.
