Hello, since the project is adjacent to two sides, the diameter was complied with and the structure is not rigid, so the analysis was done in a semi-rigid way, but it gives negative results even in 80 or even 90 rafts, so I wanted to make a rafter with beams, but it does not throw the foundation beam on the right and left facades. What is the solution? would you recommend.. can you help me, thanks in advance.
