How to Use This Calculator
- Enter the beam span in feet and the tributary width in feet.
- Input the dead load and live load in psf, including any point loads.
- Set the allowable deflection limit (span/240 or span/360) and the steel yield strength.
- Review the Required Plastic Section Modulus (Zx) and the Recommended Wide-Flange Section.
- Verify the selected section against shear capacity and deflection limits before finalizing.
