Double row reinforcement to beam

IN MY PROJECT, THERE IS A DEEP BREACH WITH 60*90 HEIGHT, BACKED TO 60*60 COLUMNS, AFTER MANY TRIALS, I DECIDED THAT THIS IS THE MOST EFFICIENT SECTION, I PLACE 12 PIECES OF 20 IRON IN CROSS-SECTION, I PLACE IT WITH 20 PIECES OF IRON BACKGROUND BY AKSESSA KEYRESIYE D.20. IF THE OVERPLAY IS DELICIOUSLY DESIGNED, WHEN THERE ARE 6 OVERPLAYS FROM THE LEFT AND 6 ON THE RIGHT ON 12 IRON, I HAVE 18 IRONS IN A SEQUENCE, SO IT IS MADE TO DISTRIBUTE THE OVERLAPS EQUALLY ON THE RIGHT AND LEFT END, NOT ON THE SINGLE SIDE? WITH 2,5 CM SPACES AND 60-5=55 MATS REMAINING 12 FLAT IRON + 6 PIECES OVERLAY = 18 PIECES OF 20 18*20=36 CM 55-36 =19 CM 19 / 17 (RANGE) =1,12 CM CONCRETE BACKGROUND AREAS FOR SETTLEMENT ARE VERY FREQUENTLY RECOMMENDED, I CANNOT FIND A TAB SUCH AS DOUBLE ROW REINFORCEMENT IN THE PROGRAM, I CANNOT FIND USEFUL HEIGHT IN THE ACCOUNT, AFTER YOU RECEIVE THE SINGLE ROW OUTPUT, I CANNOT MAKE DRAWING SUPPLEMENTS.
 
Re: KİRİŞE DOUBLE ROW REINFORCEMENT Hello, First of all, your beam span is beautiful, I can't help but say. I think you're going to do cassette flooring. It must have been a large and comprehensive project. Anyway, as you mentioned in your question, it is convenient to draw (by hand) the relevant beams with double row reinforcement, with a second row approximately 5 cm above the first row. At 5 cm, the moment carrying capacity of the beam does not decrease significantly. It is also a separate issue, but there is a suggestion that the assembly and top additional reinforcements can be placed on the floor next to the beam, provided that they do not open too much from the beam, but it is not an application that I approve and do. Yes, there is no double row reinforcement calculation and drawing in ideCAD. Good work...
 
Yes, my beam span is quite a lot of cassette slabs, I am thinking of passing the span with normal slabs, there is no problem for now, there is no problem in the slabs, deflection problem in the beams, etc. I found the optimal solution, but it took a bit of effort, my longest beam in the system has a span of 13.20. If all of them were 13 m, I would consider laying cassettes, I will put them in one row as you said in the drawing, I have no other choice, respect
 
Are your beams not stronger than columns? Wouldn't your columns remain delicate in this case? I also suggest double row manually, but without seeing the project, based on what you said.
