Calculation Basis
Assumptions & Limits
- Preset values speed up the setup but do not replace final section or material verification.
- The page is designed for fast deflection and reaction checks.
- Local code rules, long-term effects, and connection details still need separate review.
Reference Basis
- Documentation: Methodology
- Documentation: Engineering Review
- Roark's Formulas for Stress and Strain
- Mechanics of Materials references
Wide Flange Reference Setup
| Profile family | AISC W-shape / wide flange beam |
| Starting unit system | ft, kip, ksi, in^4 |
| Typical material basis | Structural steel with E about 29,000 ksi |
| Current example | 30 ft beam under 2.0 kip/ft |
| Use case | AISC-style serviceability check |
| Related checks | Column and bracing review |
Engineering Notes
- Use this page when the W-shape family is known but the exact catalog size still needs to be selected.
- The imperial-unit setup matches common AISC office practice where span, load, and section properties are exchanged in feet, kip, ksi, and in^4.
- If lateral stability, unbraced length, or combined axial action matters, continue into the stability pages rather than relying on deflection alone.
