Re: ground safety Mr. Fuatturan "The ground does not provide ground safety in my project, can you help me. My basis is maximium limits from right and left front. Thank you." My suggestions for your project: 1- Correct the errors in the geometry control, 2- You have taken C16 as the concrete value, you should use at least C20 according to the earthquake code, 3- You fixed the reinforcements of the columns by adding X, remove and recalculate, 4- Increase raft reinforcement diameter, raft slab thickness (d=80) 5- If you can increase the ground safety enlargement ratio by looking at the geology report, increase the foundation ground safety when it is increased by 25% for the foundation. (by taking concrete C20), 6- D03 and D09 should be combined and solved as a single floor on all floors, (the floors of the building should be combined on each floor or beams should be placed between these two floors) 7- 20/140 columns that you put as concrete curtain [color= #BF0000]25/140[/color] (column beam bi 8- if the columns do not save the result of calculation, do C25, if not, increase their size, 9- beams stuck from the column to the column instead of 20/60 according to the earthquake code (3.4.1.1.a) 25/ It should be 60 10- check the wall loads, 11- check the stair loads, 12- process the missing flooring in the middle, Take it easy Ünver ÖZCAN
