A nonlinear deterministic mathematic model is used to investigate the resonant response of a tall offshore structure under the action of periodic deep water waves. The added mass which is attributed to the acceleration of a body in the fluid is taken into consideration. The fundamental period of vibration of a structure is lengthened due to the effect of the added mass. An incremental numerical technique is employed to obtain the solution. The results show that even when damping due to drag is considered, the response of the structure at resonance is greatly amplified.
