Hello, I analyzed a 2-storey reinforced concrete building on İdecad 8. I solved the same plan with both raft foundation and continuous foundation. I had a few questions; * I used curtains for the basement. While I do not give an error for the R coefficient in my solution with the continuous foundation, the raft gives an error on the basis. (In both cases, the walls are defined as sub-basement.) * Doesn't İdecad already make a solution with the superstructure when analyzing? What does the Superstructure Interactive Solution in analysis settings do? Normally, when I analyze, sprain occurs in the 2nd mode, but when this button is active, the sprain appears in the 3rd mode. *The number of assembly reinforcements in the formwork plan is too high. *Finally, I set the wall load as 18 cm gas concrete (0.13 t/m2) from the beam settings, but when I look at the beam on the plan, the wall load is shown as 0.19. Attached is the work I did for my final homework. I would be very grateful if you could review and point out my mistakes. Thank you from now.
