Re: Excessive Reinforcement in Column Hello Mr. Engin, When you use curvilinear objects such as arc, ellipse while defining the polygon column section, the curves are created from short lines and the breaking points of the curve are perceived as column corner points in the program, reinforcement is placed at each corner and edge. . therefore, there may be more equipment in number. When defining a polygon column section, you'll get better results if you create the same geometry with dashes instead of curves or arcs.
