How to make Column Interaction Diagram using Mathcad

[@LeoFio]

This is great, thank you. Two things to keep in mind: for design, you need to limit the axial load to P_nmax by setting up an equation at the end that takes the minimum(P_nmax,P_n(c)). I also added a point that calculates pure tension at the bottom of the graph.

How did you add a point to calc pure tension at the bottom of the graph?

What program is it? Is your own software?

Very nice work! Good Job! BTW, what is this software you using ?

[@nahgets5279]

Many thanks! I'm using Mathcad to plot :-)

Hi! Good day. I admire your works in engineering calculations. May I know what software you are using for drawing your illustrations? Thanks in advance.❤

[@nahgets5279]

Thanks! I use Autocad and Excel.

thank you , very nice work . wich Code are you using here ?

[@nahgets5279]

I'm using ACI code. Thanks for the like :-)

Thanks 🙏

Good. But can you consider different level of longitudinal bars, not only the extreme. This is good for 2x2 and 3x3 rebar arrangements. Cheers

[@mosesd2761]

If you can prepare considering different level will be very good.

For multiple layers of reinforcement, you'd have to redefine the reinforcement inputs to calculate the total bar areas on each face and redefine the effective depth to the middle of the layers. You can do this with equations, not the way it's shown with matrix "graphical" bar layout input.

Can I get this file of column interaction diagram?

e_sat kzbin.info/www/bejne/jZLMnKl6rbCjjbc should be spelled as e_s(c) in phi(c) equation. Otherwise, my MathCad didn't run the calc
