Section Definition Module

[Marios]

Hi all,
I have some strange stress diagrams when performing stress analysis with the section definition module.
Trying to analyze a composite section it seems that when the neutral axis is in the concrete slab the web of the steel section has no streses.
When choosing from the ready composite sections from the database of the section definition module everything works fine.

Thanks for any feedback.

You picture and your strees distribution is right, Because you have loaded the section during z local axis and in the midle of cros section you have zero stresses.
Try to give the force values My and other values as zero.

Length zero this is another mess that happens when neutral axis is in the slab. My loading gives a stress distribution that looks like it came from a Mz loading and respectively an Mz loading gives a stress distribution that looks like it came from a My loading.
In both cases stresses at web are zero.

You are completly right
It seems to bee an bug of program,

I dont know why,
