The impulsive responses of a finite circular cylindrical shell filled with fluid are analyzed in order to clarify the shell-fluid coupling effect. The shell clamped ends is subjected to impulsive axisym-metric loading. Flu^^<..>gge's dynamic bending shell theory and the potential theory of compressible perfect fluid are used in the analysis. The analytical solutions in the Laplace-transformed domain are obtained. The inversion of the solutions is performed numerically using the algorithm of FFT. As a result, it is thown that the amplitude of coupled responses decreases with the lapse of time. On the other hand those of uncoupled responses are constant. When the non dimensional parameter β, which denotes the ratio of fluid bulk modulus and the rigidity of the shell, is large or the shell is thin, the coupled influences increase remarkably.
