Steel Ledger Angle Designer

14 method: required leg thickness from factored axial load (vertical leg bending about the anchor gauge g) and factored shear (horizontal leg bending with the ev+20 mm lever), resultant anchor tension Pf via the internal lever ei=(a−g)·5/6, per-anchor tension/shear from the anchor spacing, anchor layout over the supplied piece length, and a triangular stiffener check (free-edge buckling coefficient z, tmin, and Vr per stiffener). Interactive draggable cross-section with anchor elevation strip plus a 3D isometric view showing anchors and stiffeners at spacing, standard-thickness recommendation, presets, calculation-sheet text, JSON export, and print.

Screening / design-aid only. 3 Annex D. Stiffener welds, bolt-hole net sections, ledger torsion from misaligned bearing, the supported element bearing, and the wall itself are out of scope.

Combined axial+shear interaction is screened with a conservative summed utilization. Engineer review required for every output.

Use to size ledger angle thickness and stiffeners and to extract per-anchor tension/shear demands for the anchor designer. Verify anchors, welds, and the wall independently before use.
