what should i do for "floor safety negative"

[pelinimo]

Hello, I am designing 2 columns on B-1' and C'-1' axes as single foundations and the others as raft foundations. What should I do to save my single base dimensions from the "ground safety negative" error?

Re: SINGLE FOUNDATION DESIGN Hello, There is negativity in singular foundations due to negative ground pressure. In addition, in your project, "superstructure interactive solution was made" and Radye was used together with the foundation and the singular. Since the superstructure interactive solution is not made on single foundations in the program, the analysis model is formed incorrectly. A continuous foundation can be modeled for columns S02 and S07. Good work
