1. Correct excessive slab thickness

2. Increase sieze of profiles so that they support slab rather than vice versa

3. Add offset to beams

Increase sections of bars (or decrease thickness of slab).

no, the plate rests on three beams, two walls, and in the model it turns out that she still leans on the column, otherwise the points were to be on the walls. So how to make the column not taken into account?

To "reproduce" your hand calcs approach where you as far as I understand assume beams as supports that cannot move vertically you need to prevent beams from bending (e.g. increase their sizes). The columns are relatively irrelevant.

That's going to be your decision but perhaps you may re-think the static scheme of your structure. I'm sorry but this is as far as I'm able to help with my limited knowledge of your structure. Let's see if somebody else have some proposal for you Smiley Happy

Hello,

 

The RSA programme does see the beam but they are to smale (not stiff enouf) to support the floor, see screenshot pdf.

 

Your floor is 2,25m thick as the steel beams have a height of 0,24m. your floor is almost 10times higher/thicker the the steel beams.

As you see in the screenshot, the fleildmoment is in the middle, downwards. If the beams took the load, the bending moment would be upwards!

The walls on both sides wil take the load now. The steel beams and columns are just hanging on the floor doing nothing!

 

You might reconseeder your model.

Good Luck!

    

Kind regards,
