Hi, I am a student and doing my uni assignment.
I am now struggling with the support moment in a flat slab model.
It's a just simple square structures 3 bays each @ 6m span with 400x400 RC columns (both pin and fixed). I used slab wizard tools for input.
After calculation, I checked Mx against traditional methods, like simple and equavilent frame analysis to BS. I realised that the moment at the top of columns are too big compare to hand calculation or other software results like FEM-design.
I believe that it's incorrect and I tried the options "reduction of values near support" as well; it does not seem to give corrct value either. How can I reduce/ correct that?
Any suggestions are welcome.
Thanks.
