Slab self weight doesn't transfer to columns

Hello!

I'm having problem with self weight transfer to columns. I haven't had this problem before but it seems that slab self weight doesn't transfer to columns. I have attached the file.

Best Regards

Rasmus

Hi @Anonymous

I have calculated your model and axial forces distribution in columns looks ok. There is expected axial force "jump" at slab levels.

You have defined too many releases, resulting in Instability type 1 but it has no influence on axial forces in columns which seem to be correct.

Please describe issue with more details.

Hi!

Thank you for answering so quickly! Reaction from dead load (self weight) at the red circle should be around 1500kN if i calculate it manually.

Hi @Anonymous

Remove elastic ground coefficient from thickness 27 and 28. Reaction changes to 1400 kN
