Aero-eplasto-plastic behavior of a 2D square cylinder affected by motion-induced wind forces and dynamic property has been clarified by CFD. The aim of this CFD study is to obtain a change of aero-elasto-plastic characteristics due to three degrees of freedom for dynamic system (along-wind, across-wind and torsional vibrations). Obtained results are as follows; 1) In spite of the existence of hysteretic damping, the response in case of small value of the yield displacement ratio (β_m) is larger than the elastic response at lower wind velocity than the resonant velocity defined by the elastic condition. Because the natural frequency much decreases in plastic case, so the resonance occurs at the lower velocity. 2) In the case of coupled vibrations, the elasto-plastic response remarkably increases more than the one-degree-of-freedom case.
