In the static project I have made, for the double stirrup that is seen by the program, min. I made the width of B 50 instead of 40 without realizing it, I did not encounter any restrictions on this in the standard regulation. NOTE: the project is a hollow floor slab and all my beams are in size 50/30. As a matter of fact, there is only one stirrup on these beams, is there any problem??? I will be glad if you can help...
