I have a project that I solved 80 to 80 with a continuous basis. The customer requested a Raft foundation. It gives an error when I try to solve it with raft. No matter how much I increased the thickness, I could not fix the error. Please help...
The constant basic data entry in your project is incorrect. The nodal points of the continuous foundations should coincide with the column object and be connected to the panels at the nodes. (Looking at the continuous foundation Reinforced Concrete dialog, it can be seen that all stresses are calculated as zero.) Apart from this; *The elevation of the P01 panel is incorrect. -80 cm of elevation is entered on each floor. *Soil safety stress value is entered as very small as 2.2 tf/m2. I think it would be 22 tf/m2. *As there are no perimeter curtains on the 1st basement floor, it would be appropriate to enter the "upper rigid basement floor number" -2 in the analysis settings. When the above-mentioned conditions are corrected in the project, there is no problem when the foundation system is designed as raft foundation without beams, as in the attached example. Good work
