Engineering Insight

Engineering for Extreme Wind and Snow Loads

Technical overview of how structural steel and tensioned membranes are calculated to survive the world's most demanding environments.

Structural Integrity

Safety in Every Calculation

Unlike traditional buildings, fabric structures are lightweight and flexible, requiring specialized engineering approaches. Our team uses finite element analysis (FEA) to model the interaction between the rigid steel frame and the flexible membrane under varying load conditions.

Whether it's a 180 km/h wind in a coastal region or 2.5 kPa snow loads in alpine mountains, every Champion structure is site-specifically engineered to meet or exceed local building codes including ASCE 7, EN 1991, and AS/NZS 1170.

⚙

FEA Modeling

Advanced simulation of stress distribution across the truss and fabric.

❄

Load Shedding

Optimized roof profiles that naturally shed snow and reduce wind lift.

Design Standards

Compliance & Reliability

We adhere to international standards to ensure global permit approval and long-term safety.

ASCE 7 (North America)

Rigorous wind and seismic calculations for permanent and temporary structures in the US and Canada.

EN 1991 (Eurocode)

Compliance with European standards for actions on structures, including heavy snow load cases.

AS/NZS 1170 (Pacific)

Specialized engineering for cyclonic regions and high-seismic zones in Australia and New Zealand.

ISO 1461 Galvanizing

Corrosion protection standards that ensure the frame's structural life exceeds 50 years.

Dynamic Wind Loads

Modeling of peak gusts and vortex shedding for large-span clear-span buildings.

Foundation Synergy

Calculating reaction loads for concrete, screw pile, or ballast foundations.
