Rolled Sections (rolled-sections)
Purpose
Look up geometric and structural properties for standard hot-rolled steel sections — W, S, M, C, MC, L, and HP shapes — from embedded catalog data for beam, column, and connection design.
Physics & theory
Hot-rolled structural sections are manufactured to dimensional tolerances in AISC, ASTM, and EN catalogs. Tabulated properties include depth, flange width, web thickness, area , major/minor inertia , plastic and elastic section moduli , and torsion constant .
Design modules consume these properties for bending stress , buckling slenderness , and connection geometry (cope depth, flange thickness). Weight per foot derives from area and steel density 7850 kg/m³.
Catalog entries follow AISC Steel Construction Manual dimensions; tolerances and fillet radii affect connection detailing but are not modeled in the property lookup.
Governing equations
Numerical method
Catalog lookup (engine + data.ts): section designation string maps to tabulated dimensions and properties. Interpolation between sizes not performed — nearest standard designation required.
Inputs
| Parameter | Description |
|---|---|
| Section designation | e.g., W12×26, C10×20 |
| Catalog system | AISC imperial or metric |
| Property requested |
Outputs
- Full dimension set, structural properties, weight per length, depth/width for detailing.
Design codes & checks
- Indicative: Section area and inertia lookup
- US: AISC Steel Construction Manual shapes database
- EU: EN 10365 hot rolled sections (where catalog overlap exists)
Assumptions & limitations
- Properties from published catalog snapshots; verify against current mill literature for certified work.
- Simple shapes only; built-up and plated sections not in catalog.
- Torsion constant for open sections is approximate.
- Not all international section families included.
