When designing this type of structures, it may not be enough to just create the structure geometrically. You should get support from experienced engineers such as Mr. Basri (2m project), who created this geometry for you, or you should put local reinforcement bundles yourself, taking into account the stresses in the plane of the floors I have shown below (pressure, tension, and shear). In some cases, you may not be able to handle it with equipment. In this case, you need to increase the slab thickness. For example, the shear stresses F12 in the narrowed area, which is seen at the right end under the effect of only vertical loads in the picture, are not sufficient for a slab of this thickness.
