Raft base bearing strength error

[civilization]

Hello there; I'm having a problem with the foundation in a b+z+15 project I'm working on. It does not give an error when you say calculate earthquake forces from the analysis settings, but it gives an error when you do not select it. I don't want to take risks because the building is big. The project is too big, I can't throw it here. It doesn't make much sense for me to ignore g+q, but I looked at a few projects that passed from the municipality and they accepted it when they provided it with earthquakes, which frankly confused me. If I also check with g+q, the job goes to the stake. I will be glad if you help me. Thanks in advance.

Re: RAFT FOUNDATION CARRYING POWER ERROR Hello It is not binding for a faulty project to pass through the building inspection and the municipality without the mistake being noticed. G+Q upload and other uploads should be checked carefully. If you add your project, we will review it. Unver ÖZCAN

if you change the rigid diaphragm before analysis, because the file size is large Because of this, I analyzed and recorded it as fully rigid. Otherwise, the file size is around 600mb. I would appreciate if you look at both the basic and the structure in general.

Re: Raft foundation stone strength error Hello My suggestions; --Fix the errors in the geometry check, there are short objects --Soil tension at average G+Q loading19 t/m2 maximum 27 t/m2 you should do soil improvement or piling, --It saves the calculation, but you'd better turn 25/50 beams around the building's outer perimeter, --You can reduce the live loads on the attic floor and remove the wall loads, Ünver ÖZCAN

Hi Suggestions; --Fix errors in geometry control, there are short objects --Soil stress at average G+Q loading19 t/m2 maximum You have to improve the soil around 27 t/m2 or make piles, --It saves the calculation, but you'd better turn 25/50 beams around the outside of the building, --You can reduce the live loads on the attic floor, you can remove the wall loads, Ünver ÖZCAN

I will check the geometry. In the project similar to the one I had, it did not fail in earthquake strength, but in G+Q, almost the entire foundation was red, and this peojeher was licensed as such and the construction was done and it was finished. So I doubted whether I was twitching too much. I went through the reinforced concrete books and what you said was my first too. what i think is correct. If G+Q doesn't provide, it means it doesn't provide foundation even if others do. I solved this problem by solving rafter raft in ide 8 demo without ground improvement. Maybe that's why we will switch to 8. im. As you said outside the building, it would be more correct to pass drooping beams, but in my region, it is difficult to implement such beautiful solutions. The contractor even wants all of them to be horizontal beams. I can lift the loads on the roof, yes, but in my region, the rooftop is generally used for solar energy. Maybe my upload may be a little too much, but the fact that it is not at all does not quite answer the truth. I would like it to give all the loading combinations I want in the report section regarding the foundation. Currently, either g +q or g+q+e is reported, I think this is a wrong situation. Thanks again for your help.

Hello

I solved this problem by solving rafter raft in ide 8 demo without any ground improvement. If it doesn't save on a raft without beams, it won't save on a raft with beams.[/b] Note: I hope I misunderstood. I wondered how you did it. Ünver ÖZCAN

Hi, in version 7, unlike version 8, there are certain rules in the definition of rafter raft. For example, beamed raft and beamless raft plate cannot be used together in the same foundation system. In the attached link, it is explained in which situations the basic systems can be made in version 7-8:

Hi

I solved this problem by solving the rafter raft in ide 8 demo without any ground improvement.

Here's what I understand; Does the floor safety recover when you untie the rafter raft of this building foundation? I guess you are making a mistake somewhere. If it does not save on the raft without beams, it will not save on the raft with beams. Note: I hope I have misunderstood. I was wondering how you did it. Unver ÖZCAN

I have the opportunity to save it as a demo. link:

ground tension only goes up to 17 tons around the elevator curtain, which I think can be ignored. there may be errors in the project, at the moment I am only focused on the ground.

ver7 as you stated The rafter raft does not dissolve. The stresses in the raft appear as zero. If I can get a positive result, I will delay the issue of moving to 8, which I postponed just for this reason.
