Hi
I m curious to know how the column design works behind the scene. I understand the methodology used in obtaining the P-M interaction for any biaxial column design.
Then we place the Pu, Mux, Muy in the interaction diagram plot to see if it lies in the envelope. I m interested to know how this is achieved by the program.
Can you share technical details about the program ?
Thank you
Hi Sukrit,
In RCpier usermanual , the theory and Design methodology of column is provided.
In RCpier Tutorial Manual hand calculation chapter -- Example 1 and 2 - Detailed column design procedure with hand calculation is provided.

That envelope looks to be 2D for a biaxial moment. I was expecting to see 3D envelope. How do you make the 3D envelope to 2D envelope ?
Currently we are showing only 2D view of the interaction Diagram.
3D view is not available.
How do you generate the 2D envelope for biaxial problem? I see Pn and Mn on the axis. Do we know the theta (angle of rotation for neutral axis) from the Factored moments?
Design of column is not done per face but at an inclined NA; the program reports the inclination angle.
please let me know if this is the information you are looking for.
Yes Vinay, what is the formula to get the theta angle ?
