I have a raft base problem

What I did in the attached project, I could not fix the insufficient reinforcement error, I always have trouble with the raft foundation, where am I making a mistake, I would be very pleased if you could examine and tell me my mistake.
 
There is nothing I haven't done, but since version 7, I've always been having trouble with the raft foundation, I can't solve it at all, am I making a mistake somewhere, I have increased the foundation depth to 5 meters in the project, again in vain
 
You are not turning the unit of bearing capacity or ground safety tension incorrectly. What version are you solving in the demo?
 
As Ebasakin said in his friend, look at the additional accessories, one of them needs an addition. Make the foundation height around 70 cm, there is no problem when you level the additional reinforcement. You just placed some curtains incorrectly. There are small Angle objects, fix them as well. Before starting the analysis, check the geometry and correct the errors.
 
90 cm is sufficient for front size sizing. You used C30 concrete, you gave the height of the foundation 500 cm, I calculated it directly as 70 cm and the fog saved 90 cm and arrange the additional reinforcement, but first check the geometry and fix it.
 
I'm checking geometry, there are already small angled objects, I correct it last, thanks, small angled objects will not have these and similar problems, right?
 
I tried different solutions but somehow the ground safety stress cannot be exceeded. My bed coefficient is 1200 tf/m3 qt: I am attaching the 10 tf/m2 file. I will be glad if you help.
 
Hello. -Check the given floor bearing capacity, the floor can be safe as before, (if this is the case, you should make floor improvement.) -The stair thickness is low, not modeled, you can model it by putting a cantilever beam from S08 in between, -Do not put a beam on the edge of the floor space at the bottom left, the gap in the floor -Correct the (B) errors in the columns, -You can reduce the live loads on the 2nd floor, remove the wall loads Unver ÖZCAN
 
-- edited the coordinates. I entered the values I got from the ground study. -- In my soil report, 1.0 kg/cm2 is given as the Soil safety stress value. The ground report was received in March, so according to the new regulation. do i need to split my value? --I'll take care of the problem with the stairs, when I leave the bottom left floor torn, my floor thickness is not enough. -- It seems that it would not be a good result to reduce the live loads that will use my 2nd floor as a terrace. In summary, the main problem is the ground safety stress. When I try to solve it with beams and 50 cm raft, I can only find a solution when my 2 foundation beams reach a width of approximately 150 cm, which is a very absurd value. Do you have any other suggestions for the base?

You cannot enter the soil safety stress. Soil calculation bearing capacity should be approximately 10*2.5/1.4=17.9 t/m2 Contact the person who submitted the report Ünver ÖZCAN
 
I'll call the floorman tomorrow and see him. Because my core values sounded like an average of 10-11. Since I wrote 1.0 as well as 10, I was constantly having trouble with ground safety. If it turns 17, I will save the project. Thanks for information
