Slab supported by Beams

Hello.

 

I'm trying to make something really similar to this: http://forums.autodesk.com/t5/Robot-Structural-Analysis/Meshed-slab-supported-by-beams/td-p/3167096

 

But I can't support the panel by the beams. When I apply the support, it becomes also in the slab.

 

Thank you very much.

 

In attach I have upload an image.

Thank you for your answer. But as I said, my problem is similiar to the one I posted.

 

I just want the same behaviour: http://forums.autodesk.com/t5/Robot-Structural-Analysis/Meshed-slab-supported-by-beams/td-p/3167096, but I can't support my slab in that way (by the beams and not by the default pinned support).

 

Thank you

Send me model and sketch what you want to obtain

Hello Rafa,

 

If you read my first post, I've attached a image. As it can be seen, the slab is supported by the 4 pinned supports and not by the two continuous beams. If it was supported by them, the map result will be constant with higher displacement at the mid line between the beams (one direction load distribution).

 

Hope you'll understand my problem,

 

Thank you very much.

Here it is. I also would like to know why my FZ (shear force diagram for bars) isn't linear.

 

Thank you

If you have instabilities you have to correct model first

Error - h can not be 0:

I hope your material is correct

My h is 0.001. My panel is a steel grid, so it works only in one direction. I've checked only one panel supported along the edges and the results were ok, so I guess the way I've defined it is pretty close to the reality.

 

Regarding to the instabilities I'm getting, I have no idea. If I constrained/pinned the nodes where instability is reported, the model will not be the one it should. 

 

Do you have any idea what can I do?

Maybe I was not clear enough -> set h at least 0,01 cm to get rid of instabilities

OK, done! Thank you.

 

Related to FZ diagram distribution and support conditions of the panels, do you have any idea?

I do not understand.

PLease explain.

In attach: FZ diagram is discretized according to the mesh. I would like to have it linear.
