Why the(cantilever beam and slab) do not transfer together

hello
Why the(cantilever beam and slab) do not transfer together

Re: Why the(cantilever beam and slab) do not transfer togeth

What you mean for transfer?
And whats your expectation?

Re: Why the(cantilever beam and slab) do not transfer togeth

If you see the slab deflection value it will a little than the beam,

Hi Ammer,

In order to see beam-slab deformation together on 3D View, rigidity of slabs need to be considered in anaysis model. for doing so, you need to apply semi rigid diaphragm analysis on Analysis Settings. (see that 6mm deformation on middle edge of cantilever slab which has maximum value, purple colour)

Great job,
so for checking the total deflection from the beam report as show below
this values for the beam deflection including the slab deflection?!!!

Re: Why the(cantilever beam and slab) do not transfer togeth

Hi Ammer again,
your "beam deflection including the slab deflection" is not right question. That value is total deflection of beams which comes from anaysis model in which shell elements rigidity may include or may not include.

TotalDeflectionOfBeams = TotalSuddenDeflection+TimeRelatedDeflection=5.36+1.07+9.94=16.37 mm according to your screenshot.

I want to note that:
Semi diagram option: Slab rigitidy depends on it's height and slabs include analysis model. all are in together analyze. (shell elements include )
Full diagram option: Slabs has infinite rigidy, loads of slab are set to beams and then program analyzes the model. (shell elements doesnt include but theirs loads)

Re: Why the(cantilever beam and slab) do not transfer togeth

I'm asking if
The beam deflection for only beam
Or the slab deflection is same the beam deflection?

Re: Why the(cantilever beam and slab) do not transfer togeth

Sure. Must be At the same node the beam displacement and slab displacement is the same value

Re: Why the(cantilever beam and slab) do not transfer togeth

HELLO
I checked the slab report,and i found that the deflection values did not changed even when we set the semi rigid
how to solve it?

Re: Why the(cantilever beam and slab) do not transfer togeth

Hi ammer,

Deflection values are changing on either analyizing with semi rigid or full rigid diagram options.
