Load Specifications
Wind loads shown are uniform loads on a 4′- 6″ wide canopy with 2 braces.
Wind loads calculated per ASCE 7-16 Section 30.11, using net pressure coefficients on attached canopies considering contributions from upper and lower surfaces.
- Topographic factor, Kzt = 1.0
- Wind directionality factor, Kd = 0.85
- Ground elevation factor, Ke = 1.0
- Mean canopy height, hc:
- Max 60′ above ground for 4′ Projection, Exposure — B
- Max 53′ above ground for 4′ Projection, Exposure — C
- Max 53′ above ground for 5′ Projection, Exposure — B
- Max 30′ above ground for 5′ Projection, Exposure — C
- Mean building eave height, he:
- Max 60′ above ground for 4′ & 5′ Projections, Exposures — B & C
Snow loads shown are uniform loads on a 4′-6″ wide canopy with 2 braces. Snow loads shall be determined by engineer utilizing applicable codes and project-specific design criteria.
Depending on canopy width (10’-0” maximum), up to four hangers may be required per canopy section to achieve wind and snow loads.
NOTE: For more stringent loading requirements, custom engineering analysis is available upon request.
Use our Canopy Calculator to generate specifications based on load data, building codes, risk categories and building dimensions.
