for example TK36 reinforcement does not fit in the cross section."gürkan":1mj90ynw" said:sa hello I'm solving a building with a rafter raft foundation. One of the beams gave you an error (KY!) as I sent you a picture of, can you tell me what it means?

Greetings, I think you should increase the beams. If there is no obstacle on the sides of the structure, it would be very appropriate to carry the foundation outside the structure. I also suggest you take a look at ts500 ee for the ratio of foundation thickness d to beam height h for rafter raft. If there is no special reason, you can solve it without a direct beam. greetings...
1-) I solved the beamless raft by drawing the floor line from the ends of the columns, but the thickness of the raft was too large, I know it should not come out normally, but I designed a raft foundation with beams because I could not fix it. I am sending you the project that I solved with a beamless raft. I would appreciate if you inform me about why it is so thick. 2-) Do I need to define a column header with a thickness of 0 when defining raft foundation (for punching verification) (Note = Since the file size exceeds 3 mb, I deleted the raft foundation excluding tiling lines. When you receive the project, you only need to define slab on the rail. When I solve it, even a 200cm raft foundation gives a positive result. didn't. thanks

if the soil tension control is done according to the average tension, the foundation with 65-70 cm is sufficient. However, I recommend removing the brackets from the column at least 100 cm. If it will not be controlled, either soil improvement is made or the foundation base area is expanded or piled raft (if it reaches hard ground) n) is done. I think one of the main problems of this building is that the curtain is too long. Instead, if you prefer curtains with a size ratio of around 1/10 and a more homogeneous distribution throughout the building, you will see that the foundation is relaxed. however, if you model your curtains as a shell (I sleep like that) and analyze it, you will see that you are more relaxed.

I suggest you model the panels as shells in version 6 of the project. When you model it as a shell, the panel loads will spread to the ground with finite elements and the stress distribution on the ground will be more homogeneous. Good work...

It is not possible to transfer the 6 VERSION file to version 5. I recommend you to upgrade to version 6 or contact ide officials. There is no shell modeling in the version anyway. Pay a little difference and pass 6."gürkan":220vs21y" said:I am using version 5.511, the file you sent did not open in my program. What should I do.
