Good evening, Regarding the analysis of existing buildings, some beams (or columns) can use different diameters of reinforcement. For example, 2Ø12 + 2Ø16 flat reinforcement was used on top for a beam. But I could not define it in the program. I wonder if I Did I not see it or do we not have the opportunity to define it in this way yet? Because otherwise we have to choose a reinforcement that is below the existing reinforcement area, such as 2Ø14. And it is not easy to find reinforcements that will give similar values every time. Good work, Yağmur Can KOÇAK[/ quote] Hello, It is possible to enter different rebar diameters as major and minor in columns. However, it is important to be able to provide total rebar area for both longitudinal and transverse reinforcement. In short, a data entry depending on the diameter of the reinforcement is not required. Columns, beam supports and You can arrange the reinforcement in any diameter to provide the total reinforcement on the panels.In addition, there is stirrup tightening in the existing beams and columns o It is also important to inform you whether it is loupe or not... The relevant option is available in the beam, column object settings. Good work...
