How to Use This Calculator
- Enter the design moment and shear in kip-ft and kips respectively.
- Set the web height-to-thickness ratio and flange dimensions.
- Input the steel yield strength and the unbraced length of the compression flange.
- Review the Section Modulus Provided, Flange Local Buckling ratio, and Web Slenderness check.
- Verify the Lateral-Torsional Buckling reduction factor to confirm the section is adequate.
