Equivalent Frame Method- Column Axial Load

[hoshang]

Hi all,
I tried to find out column axial load for Example 13.3 in Nilson's Design of Concrete Structures textbook, SI units, 14th so I can compare it with Autodesk Robot Structural Analysis.
Please find attached link:

Robot results 335.71kN
My hand calculation results: 375kN
Is it comparable? Is my hand calculation correct?

you have not applied the correct boundary condition

My mistake. The support direction (beta angle) was not correct.
Thanks. You've been of great help.
I assume you are DonBAE in Robot Forum.
