How to changing pin support of slab to allow for some rigidity in robot model

I have modelled a precast slab as simply supported in Robot.

In reality, because there is top rebar over the support, it will have  bit of rigidity so will not be simply supported.

How best can i show this in my simple model?

 

Thank you

Hi @Tmanzz 

Use an orthotropic slab with rigidity in one direction (according to global axis)

Hi @Simau ,

The bending moments at the supports are still zero. While mid-span is still maximum at wl2/8. 

How do i amend the support condition so some of the moment is taken by the support as hogging moments?

thank you

Now I understand you

You may test some elastic supports, but you must estimate Rx value
