I have concrete building model. When I was checking axial loads of the column I noticed that axial force between columns on 5th and 4th floor had very small difference compared to other levels. On investigating problem further I found that self-weight (case 1) of floors is not transferred to columns. All other loads look OK. Can somebody guide me on what’s wrong with my model? Model is too big to upload on site so i have uploaded on my dropbox.Heres the link for model.
Example
Difference in axial load between members 151-167 is 263.1-211.34=51.76kN. This is for load case 1-DL1
But
Difference in axial load between members 135-151 is 274.58-263.1=11.48kN for same load case.
