Beamless Raft Foundation

[Ahmet L. Çomaklı]

Attached, I am sending the project of the reinforced concrete system where we will place the underground fuel tank. The raft foundation thickness does not save. According to which regulation does the program calculate the minimum values for the beamless raft foundation height? When you set the upper rigid basement floor number to -1 from the analysis settings, there is no problem. Do you have a problem with data entry? We provided the load transfer from the foot of the tank to the raft foundation with a linear load. Can we see/how do we see these loads in a 3D frame? Good work.

When I analyze the project you sent, it saves me, sir, there is no problem, sir, my version is 7.022, but..

Thickness control in beamless raft flooring It does it according to the H>=Ln/30 condition given for beamless floors in TS 500. When the analysis is done in the project, the raft slab does not give any thickness warning.
