1 · Input data
Every parameter below is required. Selecting a W-shape reads its section properties straight out of the AISC Shapes Database; the other parameters are entered by hand. Press Solve the compression check when the card is complete — if anything is missing or malformed the page opens a pop-up naming each parameter and computes nothing.
Bracing and effective lengths, by axis
Each row is one axis. Give the effective length factor and the unbraced length between braces for that direction; the check uses the axis with the larger KL/r, and the torsional term uses the larger of the two lengths.
2 · Solution
No solution yet — complete every input in the card above and press Solve the compression check. This card stays empty until a solution is computed, and it is emptied again the moment any input changes, so a displayed solution always belongs to the inputs on screen.
