Every surface is rendered in 3D and coloured by its design pressure, with the value on the face and an arrow showing whether the load pushes in or pulls off. Turn the model, switch wind direction, and step through load cases — then the same diagrams print into the report.
ASCE/SEI 7-22 · Chapters 26–30
Every pressure zone, coefficient, and load case from ASCE 7-22 — computed step by step, shown in full, and rendered as an interactive 3D model you can turn in your hand — then exported as a report you can put straight in the project file.
Built and maintained by a licensed structural engineer.
Coverage schedule
One tool across the whole wind scope — no jumping between spreadsheets for the sub-mode you happen to need today.

Capabilities
The engine follows ASCE 7-22 to the letter. The workflow keeps you moving through it.
Every calculation exports a clean report with inputs, results and code references — ready for the project file.
Each step shows the governing equation, the coefficients used, and every intermediate value behind the result.
Organize work in a folder tree and reopen a whole session — every sub-mode — exactly where you left it.
Closed-form coefficients where the Commentary provides them, with figure-rounded values available when you prefer.
Your firm admin adds or removes engineers as the team changes, within the seat count on your plan.
Runs in the browser, on any machine — office desktop or a laptop on site. No licence keys to chase.
Pricing
Full wind scope on every plan. Add or remove engineers anytime. Thirty days free. Tell us about your team and we’ll set up your trial — no card needed to start.
Professional-use note. The Wind Load Calculator is a calculation aid implementing provisions of ASCE/SEI 7-22. It does not perform engineering services and is not a substitute for engineering judgment. The licensed engineer of record is solely responsible for verifying all inputs, outputs, applicability, and code compliance before any reliance or use.
