DYNAMIC CHARACTERISTICS OF A LARGE UNDERWATER SHELL OF REVOLUTION (2ND REPORT) - DYNAMIC RESPONSE ANALYSIS

In this second report on the dynamic characteristics of an underwater large rotational shell, the paper focuses on the seismic response of the shell to horizontal ground motion. The natural modes which were obtained in the previous paper are used to estimate the seismic responses, which are based on the theory of power spectrum. The response of the shell in water is very different from that in air because of the effect of large added mass and the seismic input spectrum, and so this kind of numerical analysis of fluid-structure interaction problem has to be analyzed numerically in advance in the design process. The features of dynamic characteristics of the half drop shaped shell that the authors proposed are also discussed.
