摘要：
For studying the characteristics of Steel Catenary Riser (SCR), a simplified pinned-pinned cable model of vibration is established. The natural frequencies, the normalized mode shapes and mode curvatures of the Scr are calculated. The fatigue damage of the SCR can be obtained by applying the modal superposition method combined with the parameters of S - N curve. For analyzing the relation between the current velocity and the SCR’s fatigue damage induced by the vortex-induced vibration, ten different current states are evaluated. Then, some useful conclusions are drawn, especially an important phenomenon is revealed that the maximum fatigue damage in the riser usually occurs near the area of the boundary ends.
