About passing long span

You can't pass with these sections, you have to widen and deepen the k39 and k40 beams and you have to change the direction of the ribs in between. I recommend that you do not exceed 200 m2 of flooring in one piece.
 
In this way, you will have difficulty in overcoming the deflection problem in a flooring. In its current form, the conditions of the regulation are not met. Their cassettes should be larger and higher in height. Maybe even the system should be divided into smaller tiles. In this case, deflection problem will be encountered in the main beams. The beam dimensions are too large, and this time the columns will remain very delicate. This clearance value is great in such a design for a classical reinforced concrete system. It is a considerable clearance even for a steel system. Maybe a solution can be obtained with steel composite flooring or pre-tension-post-tension systems.
