Hello, my question, when I examined the report of the beams, I saw that there are combinations with the capacity ratio greater than 1 (such as 1.021,1.008) in the capacity design. It appears in the effect diagram as well. This capacity ratio must be the shear force and moment relationship. If this is the case, the beam did not issue a capacity warning. Am I interpreting it wrong? I would be glad if you help. Good work.

Hello, the capacity ratios in the Beam Reinforced Concrete/Capacity design dialog are the ratios under the effect of biaxial bending and axial loading. And these ratios are greater than 1. If it is too big, no warning is given in the report. By increasing the beam upper flat, lower flat and body reinforcements, these ratios can be reduced below 1. Good work
 
Mr. Levent, do we need to reduce this ratio below 1 by playing with the equipment you mentioned? Do we have a chance to see the beam capacity ratios in one place or do we have to enter them one by one?

Beam capacity ratios are given in the Kiris Reinforced Concrete dialog. You can examine the beams respectively by selecting the "All floors" option in the Kiris Reinforced Concrete dialog and clicking the "forward" and "backward" arrows at the bottom of the dialog.
 
Hello again, Mr. Levent, you said that the situation on the subject is in your notes, but we did not see it in the update. Namely, I spend more time correcting these capacity ratios than the project. If the column or beam elements in the program are working above their capacity, is this not an error? If it's a mistake, why can't the program equip these capacity ratios below 1 or why not? Since we solve the reinforced concrete system semi-rigid, it is not very pleasant to intervene in the reinforcement by hand, because the behavior of the structure will theoretically change with each reinforcement intervention. Thanks in advance for your comment...
 
Reinforced concrete design calculations in the program are made using the bearing capacity method, which is calculated in TS 500. TBDY 2018 and Ver. With version 10, fiber model approach and mander model (material model in TBDY Chapter 5 applied within the framework of TS500 rules) were added to the program as capacity design. There may be differences in the results between the two calculation methods due to account acceptance. The request for automatic design according to the capacity ratios has been conveyed to our R&D team. We recommend considering the capacity ratios in reinforced concrete element designs. Good work
