How to Use This Calculator
Enter each requested value using the displayed unit. Replace the example defaults with source-specific values and review all assumptions.
Formula & Methodology
The calculator applies the displayed formulas directly to the entered values. Supporting outputs expose important intermediate calculations.
Worked example
For a simply supported member with center load, use a load-type factor of 4 because maximum moment is P×L/4. Other load patterns require different factors.
Single angles are prone to unsymmetrical bending, twisting, local buckling, lateral-torsional buckling and connection effects. Deflection, shear, holes, corrosion, welds and code load combinations are not checked.
Do not use this estimate as a structural design or safety approval. A licensed structural engineer must verify member orientation, bracing, connections, loads and applicable building code.
