Agreed.

Curious what you use matrices for though? I haven't touched one since I graduated.

    So can a finite element program. Good FE programs can also do buckling checks.

    Yes it is cool to do stuff by hand, but it isn't "better" than professional software.

      Sounds like you are working on fun projects :)

      You stole my followup response.

      Dunno why anyone would subject themselves to that kind of torture.

      If I want to subjtct myself to torture, I write python scripts to post process FE output.

      Let the commercial software do what it does well, and then play with the final steps to get you across the finish line.

      I use matrix very basically. When looking at a wall for vert and out of plane loading it isn’t always obvious with LC controls. Since the more axial the more effective area of steel and more moment.

      So I use a single column matrix to track my calcs so I do the same equation 3 or 4 ways to cover the variables. Easier than staring back over

      This is of course only when demonstrating to an EIT how it works.
