⚠️ 3D model upload & wind zone detection is still in beta. Meshes are classified with an in-browser trained MLP (IFC type hints when available); wind zones use surface normals vs wind. Low-confidence meshes stay uncoloured.
AS/NZS 1170.2 Cl 5.3.4 — internal pressure volume factor from opening ratio (see hover).
From AS/NZS 1170.0 Table 3.3 using Importance Level and Design Life above.
Run site detection to generate topographic profiles.
Professional Wind Load Analysis — AS/NZS 1170.2:2021
StructuralWind is a professional wind load analysis tool built for structural engineers, building designers, and construction professionals across New Zealand and Australia.
Our mission is to make AS/NZS 1170.2:2021 wind load calculations fast, accurate, and accessible — reducing the time spent on manual calculations so engineers can focus on design.
🎁 New users can start with a 1-month free trial on paid plans to evaluate advanced analysis, reporting, and collaboration features.
Interactive 3D building model with real-time pressure heatmaps, wind flow particles, and pressure arrows.
GPS-accurate site location with terrain category mapping, shielding analysis, and topographic multipliers.
Full directional wind speed analysis with Md, Mz,cat, Ms, and Mt for every cardinal direction.
Detailed, clause-referenced reports compliant with AS/NZS 1170.2:2021 — ready for council submissions.
External, internal, and local pressure coefficients per Tables 5.1–5.6 with net pressure calculations.
Change any parameter and see results update in real-time — no waiting, no page reloads.
Import IFC and supported mesh formats to analyze real project geometry in-browser with face-level wind context.
Render roof and wall local pressure zones visually and align them with tabulated local pressure outputs.
Share projects with your team, track who changed what, and keep wind analysis workflows aligned across multiple engineers.
All calculations are performed in accordance with:
