In a project I did in ide static 6.0012, "Total Nd in X direction is greater than 0.45* total Nk 1.Bodrum ,Nd=28,885,0.45 Nk=0 and in Y direction total Nd is greater than 0.45* total Nk 1.Bodrum ,Nd=28,885 ,0.45 Nk=0" errors came out. What should I do to fix it. Also, I checked the loads on the columns on the ground floor more than on the basement floor. There is no irregularity in the loads.
 
This error does not occur easily. You have to work in a model that is very unstable and critical for loads, or there are problems in your data entry, especially in vertical continuity. Examine your system in a 3D frame view. There may be connection problems. In particular, examine the main points. If you can't find the problem, you can add your project here... Take it easy...
 
thank you.ide 6, this is my first project since I just switched. I checked but I couldn't see any error. I'll send the file, can you take a look. Maybe there is something I missed.
 
hello, when you start the analysis, when you select "create a single rigid diaphragm in the floors" in the message that comes up, the error disappears. Your comment is yours. Can I ask why you solved the structure as normal ductile, I think your columns are too small for me, although the program does not give an error, I am in your place. If I were you, I would increase the narrow side of the columns to 30 cm.
 
In the basement floor, as required by the system, beams are defined one above the other, and these beams divide the columns they sit on into a small piece and the floor in that area is at a different level from the main floor. That's why the program asks what you want to do with the message that your structure has more than one rigid diaphragm. You do not need to accept different rigid diaphragms for a single slab. During the analysis, you can make calculations with the option "create a single rigid diaphragm within the floors".
 
Since the total height of the building does not exceed 25 m, I solved it normally. and I bought 4 in r. Can you tell the difference between creating a single rigid diaphragm in layers and creating more than one rigid diaphragm. In what situations should I choose these fringes. I am quite new to these subjects. The project is already a sample project. so it's already done.
 
"Total Nd in X direction is greater than 0.45* total Nk 1.Bodrum ,Nd=28,885,0.45 Nk=0 and in Y direction total Nd is greater than 0.45* total Nk 1.Bodrum ,Nd=28,885,0.45 Nk=0" errors occurred. said Mr. Emre, where do these errors appear in the report? thanks
 
Sorry, I realized it was in the report section... and I didn't examine the project much, but in this project, I saw that the eccentricity of the lower column and the upper column did not intersect.
 
what if I couldn't see an option to create a single rigid diaphragm in the floors during the analysis, it gives me the same error, I couldn't solve it, I would appreciate it if you could help me.
 
It gives a project error because the sum in the X direction is greater than nd 0.45 times NK and in the Y direction the total nd is greater than 0.45 times NK. What should I do?
