Canopy “break away” ties

A fabric covered courtyard canopy at a large high-rise office complex in Houston required specially designed “break away” roof attachments. The detail involved using a combination D-ring and extra-high tensile strength nylon zip ties calculated to break at the required high winds release measure of 112km/hr. The fabric roof has tabs sewn underneath which hold the D-rings, which in turn are strapped to the normal canopy lace rod welded to the canopy frame.
