A square cylinder is typical shape of a building and the bridge beam, therefore the grasp of its aerodynamic characteristics is important for the wind-resistance design. However, the study does not advance in comparison with many cylinders and is insufficient to grasp those. It is clarified that the pressure from wind decreases by changing the shape of the square cylinder from the study of Tamura and others. We focus the shape of the square cylinders with the step. The purpose of this study is to clarify the influence that steps gives in aerodynamic characteristics. The number of steps is changed and the drag measurement experiment using the wind tunnel and the visualization experiment using the water tunnel is made.
