Hello, I couldn't solve the basic part no matter what I did, when I solve it in ide 7, there is no problem, but when I solve it in ide 8.5, I can't save the foundation hope you can help
 
Hello there; ---you have defined both continuous foundation and raft foundation. choose one of the two---probably you always wanted to define slab on foundation, but you did it wrong. You don't need to define slab on foundation all the time, you can show it in the drawings. ---but my suggestion would be to lay a raft with very low floor values and define a sub-basement curtain. ---only Q12 selected for raft foundation reinforcement; you should increase. (like Q14, Q16) If you do these, you will not get any errors. good work.
 
Even if I increase the diameters of the iron, I encounter the same result. Could it be a problem with the nodes? In the region where we work, the landlord and the municipality find the foundation suitable in this way, we often use it. but this is the first time i got such error. more precisely, I couldn't fix it for the first time. I do not have full command of ide8, I was using 7 before. I wonder if I'm missing a point. Isn't there a chance to fix it without playing with this foundation type? I would appreciate it if you could help Ground values are attached.
 
There are no problems with soil tension in the foundations in your project. Rather, there seems to be a lack of reinforcement in the foundations. Change your base dimensions. Such a high foundation beam is not suitable for a 3-storey building in total. In your project, I made your foundation beam widths of 60 cm and the heights of 80 cm. There is only one lack of foundation reinforcement, and you will get the result when you edit the stirrup reinforcement. (I sent the attached file by suggesting a small change in its basic form.)
 
Thank you for answering, but the ground survey report limits the minimum foundation width to 1.20, so it is not possible for me to decrease the foundation Height, as a result, can we not solve this foundation type with the design in my project?
 
You are misinterpreting the ground report. Friends who have already done ground studies have started to write everything down. If we let go, they will almost do the project. The Df mentioned here is about the depth of the foundation, not the height of the foundation. The engineer determines the foundation height. By the way, I can't pass without saying a few sentences about these floor reports. Nowadays, I see the following in the ground reports: - Raft foundation should be made. It's not a floor worker's job to write them down. The building importance factor is a regulatory thing. Whatever they write, it is a value that we should take according to the structure we make. The sentence "The raft foundation must be made" is also a rather unnecessary and absurd sentence. Again, one of the absurd and unnecessary sentences: Earthquake regulations must be followed. :D So if it doesn't write on the floor report, it means you can do it as you wish. You are looking at the contents of the reports, sufficient information about the ground; bring it right.... There are more interesting sentences, but I'll leave something to share with other friends.
