EARTHQUAKE RESPONSE OF ELASTIC AXISYMMETRICAL ROTATION SHELL IN WATER

Earthquake response analysis of an elastic axisymmetrical rotational shell in water is presented as a structure-fluid coupled vibrational problem. Added mass used in this paper wad obtained by boundary element method and was given as matrix form which could be combined directly into structural mass matrix by finite element method. The numerical calculating procedure of added mass induced by elastic shell motions was proposed by Saijo and Nishiwaki (1991). Using this calculation method to coupled vibrational response, the behaviour of a submerged elastic axisymmetrical rotational shell is studies under the condition of water-depth-variations by two types of hyberboloidal shell models. The validity of calculated response values under an earthquake assumption is examined by the comparison with experimental data. Through these considerations, some remarkable conclusions are introduced.
