MWFRS Wind Load Calculator

The calculator supports moment frames, braced frames, shear walls, rigid frames, and combined lateral systems. Handles steel, concrete, wood, and masonry structures. Calculate wind loads for low-rise and mid-rise buildings across all Risk Categories.

Yes. This calculator is designed specifically for licensed structural engineers and engineering firms. It provides detailed calculations, assumptions, and references to ASCE 7 sections. Users should have engineering knowledge to properly interpret and apply results.

Both ASCE 7-22 and ASCE 7-16 are fully supported. You can toggle between versions for any project. Most jurisdictions have adopted ASCE 7-16, but ASCE 7-22 adoption is growing. Check with your local building department to confirm which version applies.

You'll need: building location, dimensions (height, width, length), number of stories, roof pitch and type, exposure category, Risk Category, topographic data, enclosure classification, and lateral system type. The calculator handles both directional and envelope procedures.

Yes. The calculator provides complete MWFRS analysis including base shear, overturning moments, story shears, story forces, and wind pressure distributions on all building surfaces. Results include load combinations per ASCE 7 Section 27.4.

Yes. Reports include all calculations, methodology, and references required for professional engineering review and sealing. Licensed engineers can review, verify, and seal the calculations per state licensing requirements for submittal to building authorities.

Yes. The calculator supports rectangular, L-shaped, T-shaped, and other irregular building plans. Handles buildings with setbacks, varying heights, and mixed roof configurations. For highly complex geometries, contact support for custom analysis options.

The calculator automatically accounts for torsional wind loads per ASCE 7 requirements. Calculates load eccentricity and torsional moments for both rigid and flexible diaphragms. Includes provisions for accidental torsion and amplification factors where applicable.
