Have a nice day. When I solve my system with 40 a 70 columns, a total of 14 major and minor reinforcements are calculated with a few reinforcement differences on some floors. But I have to make some of my columns polygon. When I solve the same system with the same loads and some of them as polygon columns, the number of reinforcements in polygon columns, especially on the ground floor, is too much. My floor heights are in the basement 3.00 m from the ground floor 4.50 m from the 1st floor 3.50 from the 2nd floor 3.50 I think the reason for this is that the polygon columns change value according to the floor height. Let's summarize briefly. When I define a normal column, all columns give the expected reinforcement on each floor. When I solve the polygon, the reinforcements are different on each floor. I will be glad if you can help. Have a nice day. Sent from my SM-G610F using Tapatalk
