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

Engineering Notes
- CHS members are efficient where torsional symmetry and clean all-round bending behavior matter.
- This page starts with a full-span uniform load because circular hollow sections are often checked under continuous distributed service loads.
- If local attachments or eccentric brackets control the real job, supplement this result with local wall and connection checks rather than relying on global beam response alone.
