apeSteel

Use whenever the user is working with apeSteel — the composition-based, strictly-typed Python library for steel member design per AISC 360-22, AISC 341-22, and AISC 358-22 (plus EN 10365 IPE/HE shapes). Triggers on building Element composites (section + SteelMaterial + Bracing + construction), running AISC checks via the Element facade (classify_flexural, classify_axial_compression, classify_seismic, flexural_strength_F2/F3/F4/F5, shear_strength_G2, compression_strength, combined_strength_H1, torsion §H3), the BeamCheck facade (run_full_beam_check), pulling shapes from AISCv16Catalog / EuropeanIPECatalog, working with frozen Report dataclasses and AISCClauseReference citations, the canonical N-mm-tonne-s baseUnits convention, the geometry classes (DoublySymmetricISection, SinglySymmetricISection, ChannelSection, RectangularHSS, RoundHSS, TeeSection, DoubleAngleSection, SingleAngleSection, RectangularBar, RoundBar), and BeamColumnConnection seismic checks (panel-zone shear, column-flange tension, doubler/conti

apeSteel is a composition-based, strictly-typed Python library implementing AISC 360-22, AISC 341-22 (seismic), and AISC 358-22 member-level steel design (plus EN 10365 IPE/HE shapes). Use this skill whenever the user is writing, reading, debugging, or reviewing code that imports apeSteel: building Element composites (section + SteelMaterial + Bracing + construction), running AISC checks via the Element facade (classify_flexural, classify_axial_compression, classify_seismic, flexural_strength_F2/F3/F4/F5, shear_strength_G2, compression_strength, combined_strength_H1, torsion §H3), the BeamCheck facade (run_full_beam_check), pulling shapes from AISCv16Catalog / EuropeanIPECatalog, working with frozen Report dataclasses and AISCClauseReference citations, the canonical N-mm-tonne-s baseUnits convention, the geometry classes (DoublySymmetricISection, SinglySymmetricISection, ChannelSection, RectangularHSS, RoundHSS, TeeSection, DoubleAngleSection, SingleAngleSection, RectangularBar, RoundBar), and BeamColumnConne
