This paper reviews the progress made during the past decade on vortex-induced vibration (VIV) of long slender cylindrical structures. When the aspect ratio, which is defined as the ratio of length to diameter for cylindrical structures, is large enough (10 2–10 3), some unexpected phenomena occur, e.g., dual resonance, multi-mode vibration, unsteady lock-in, the third and higher harmonic fluid forces and traveling wave dominant response, as summarized in this paper. In addition, a brief outline is given of numerical methods used in predicting the response of long slender cylinder undergoing VIV.
