NOTEAssumptions & limits of this model
Single-span only: simply supported or cantilever fixed at the left support.
Loads act in the plane of the web, downward, through the shear centre. No axial force, no torsion, no biaxial bending.
Elastic analysis; deflection by numerical double integration of M/EI over 1000 stations.
C₁ is user input. The default 1.13 suits a UDL on a simply supported beam with end fork supports. Change it for other cases — 1.00 uniform moment, 1.35 central point load.
LTB uses the rolled-section case, EN 1993-1-1 §6.3.2.3, with λ̄LT,0 = 0.4 and β = 0.75.
Class 4 sections are reported, not designed. No effective-width reduction is applied.
Shear buckling is checked against the §6.2.6(6) threshold only; no post-critical resistance per EN 1993-1-5.
Section properties are tabulated values for European hot-rolled profiles. Root radii are drawn approximately; they are exact in the property data.
