Impulsive responses of a circular cylinder filled with fluid and subjected to uniform load are analyzed. The coupling effects on the responses are investigated using analytical solutions and approximate solutions of mass-spring models. Impulsive responses of the cylinder are divided into three groups with a nondimensional number β=KR(1-ν^2)/Eh where E, ν, h and R are Young's modulus, Poisson's ratio, thickness and radius of the cylinder, respectively, and K is the bulk modulus of fluid. For β of the order of approximately one, the coupling effect on the responses appears remarkably. When β<< 1, the fluid motion hardly influences the behavior of the cylinder. When β>>1, the behavior of the cylinder is dependent on the fluid motion.
