I'm sorry, I want to ask a question. When I analyze a 5-storey building, there are 2 pieces of 16 iron in the 30*60 column mirror. even when I look at the sample projects, 3 pieces of 14 reinforcements seem to be sufficient for the column mirrors of even a 10-storey building. but when I go around the constructions, I see 3, 4, and even 5 16-inch irons in the 30 section on the column mirrors of most 4 or 5 storey buildings. irons are seen frequently in the middle parts. What could cause this number to increase in the results of analysis with other programs? Or, what is the reason why 2 16 steel irons appear as standard in solutions with idecad. Although the number of floors increases, the number of reinforcements in the mirror does not change.
