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. Section F6 has no unbraced length and no moment-gradient factor — weak-axis bending capacity is not reduced by Lb, Lp or Lr — so the card does not ask for them. Press Solve the flexure check when the card is complete: if anything is missing or malformed the page opens a pop-up naming each parameter and computes nothing.
2 · Solution
No solution yet — complete every input in the card above and press Solve the flexure 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.
