Mr. fuatturan "FLOOR SAFETY CANNOT SAVE ANY KIND. VALUES FOR THE FOUNDATION LIMIT VALUES" My suggestions for your project: 1- Put a mezzanine beam between S19-S20 to support the stair mezzanine landing, 2- K32 to support the staircase to the floor -Place beams between K36 beams, take the load of stairs, 3- When you make a solution with the ground safety you entered, your ground safety does not save. the value of your floor safety is not bad. With the C group soil, not the D group, 15.00 t/m2 soil safety, geology eng. If it changes with the D group, then it saves the ground by taking the enlargement ratio to 25%, (the ground safety can be increased by the geological engineer since the values are very close to the current values and the given ground safety is about 2.5-3.) Solve the superstructure interactively, (When solved by taking R=7, BP03 and BP04 do not save, there is no problem when the thickness is increased by 5 cm.) 5- Check the wall loads. 6- If the above suggestion is not for the floor, you need to improve the floor. 7- It would be better if you solve the beams without piles.
