Anchoring Requirements (Non-Certified Tents)
Non-certified tents are not engineered to meet specific wind loads. Wind loads are approximate and are generally
rule of thumb calculations used in the industry based on actual field experience. Windload of a non-certified tent
will vary to a maximum of approximately 30 to 50 mph dependent upon the style of type of tent. The structural
integrity of the tent may exceed the soil's holding capacity even at wind loads of 30 to 50 mph.
Frame tents require approximately 1000 to 2000 lbs of holding power per anchor location (dependent on the size
and style of the tent). For safety of all occupants, evacuation is recommended if weather becomes severe.
Severe storms have micro bursts of wind that may be recorded far in excess of the storm's highest winds. The
installer is responsible for properly securing the temporary structure (tent). Soil conditions will vary and the wind
loads that the temporary structure can handle could be significantly below its wind load capabilities.
*Holding power is based on firm soil conditions. If other conditions prevail, the holding power will
decrease and alternate anchoring methods are required.
Installed Tent Inspection
Staking: Check all stakes for signs of movement.
Tensioning: Check all ropes/straps for proper tension and make sure that the tent top is set for proper drainage.
Poles: Check that all poles are properly aligned, securely tied, and structurally sound.
Sidewalls: Check that they are properly secured as needed.
Special Considerations: Make sure that the installation is in compliance with all local building, fire, and public
safety codes.
