Composite Stress Calculation in MIDAS CIVIL

Question:

Hi,
I have a doubt regarding composite section stress calculation in MIDAS. I was checking it for self-weight only in post construction stage (not considering time-dependent effects). The section should behave as a composite section. But stress distribution appears like slab and girder are bending independently.
Please explain the detailed calculations for stresses in this case?

Answer: Hello User,

Thanks for your interest in Midas. PFA the screenshots showing the BeamStresses for Part 1 - Girder and Part 2- Slab for "ST: Selfweight of girders".
Also, see the attached deformation animation for Composite Girders. It can be observed that composite action is reflected in the analysis.
