Re: stapling error First of all, I can say that the fixed loads on the slab are too much. You have entered 0.500 tf/m² constant load on all floors. I don't know why you prefer such a high load. If you take this to reasonable levels (0.15-0.25), you will probably have a lot of problems solved. The program automatically takes rib tooth weights and slab weights. Again, I can say the following for beam loads: If there is a wall load you entered, there may not be a live load. (can be entered) Or if there is a live load (i.e. there is no wall on the beam), then there is no need to enter a wall load. Other than that, I can't say much because I don't know how the roof is used, but if there is no area for use on the roof, floor live loads, beam wall and live loads can be reviewed. If the punching problem does not go away despite all this, you can play with the dimensions and directions of the columns, add columns to the system (to take the load of the forced column), or increase the thickness of the foundation. It would be correct to solve with a semi-rigid diaphragm. Include the ladder in the system. Do not forget to overhaul the column beam shear safety issues besides punching.
