| Quantity | Major axis | Minor axis |
|---|---|---|
| I [cm⁴] | 1943 | 142.3 |
| W [cm³] | 194.3 | 28.47 |
| σmax [MPa] | 22.8 | 156 |
| δmax [mm] | 1.81 | 24.8 |
Both columns use the same total load, span, material assumption and catalogue edition. Rounded values are for display.
Add self-weight exactly once
q = qexternal + μgCalculate moment, stress and deflection
Mmax = qL²/8 ; σmax = Mmax/W ; δmax = 5qL⁴/(384EI)Compare orientations and interpret the limits
The links load the specified catalogue profile, axis and inputs. The stress calculator also uses an illustrative allowable stress of 160 MPa: replace that assumption for your own problem. Neither that comparison nor a deflection alone establishes safety or code compliance.
Lateral-torsional buckling, section classification, shear resistance, local effects, connections, load combinations and project-specific serviceability limits are not checked. Lateral restraint and actual support conditions need separate verification.
