This paper deals with the evaluation on aerodynamic characteristics of a square cylinder oscillating in the across-wind direction. Two-dimensional flow calculation was executed by using k-ε with a modified production eddy viscosity model. Calculated results were compared with experimental ones mainly obtained in this study. Firstly two patterns of aerodynamic response with different mass-damping parameters were predicted. Secondly unsteady lift acting on a oscillating cylinder were predicted. Although a slight difference was observed between predicted unsteady lift coefficients and experimental ones, accuracy in predicting aerodynamic response was far better than that of unsteady lift coefficients.
