Hello, In some curtains and columns, various loading combinations that exceed the envelope of the capacity diagram are observed in the diagram, but there is no warning about any problem in the project reports, pre-report controls, reinforced concrete menus. What is the reason?
 
Hello, Re-evaluate according to the following information, if you think the problem is valid, add the project to the message. The yellow area in the picture indicates the area limited by the N and M values of all combinations... The curve with the blue line shows the element capacity. The blue and red dots (crosses) within the yellow area in the picture indicate the lower and upper nodes of the element, respectively. As a result; the yellow area should stay inside the blue curve...
 
Hello Mr. Hakan. When we examine it within the framework you stated, we see the problem I mentioned in the first messages. the file is attached. We will be pleased if we can identify the problem and find a solution. good work.
 
Hello, You need to consider the situation that the program shows in the capacity diagrams in the column design. The system is weak in the minor direction... the column major moment is close to zero, the minor moment is large and the normal force is close to zero. 1. You can enlarge the column in the minor direction. You can approximate the shape of the column to the square. or 2. By making the system stronger in the minor direction, you can make the column receive less moment. or you can increase the 3rd column reinforcement. We also noted that the program does not give a warning when there is an effect beyond the capacity diagram. Good work...
