STRUCTURAL ANALYSIS OF A FIBERGLASS ANTENNA TOWER
The Federal Aviation Administration requires a 61 m (200 ft.) obstacle free zone (OFZ) on each side of airport runways, but allows the placement of break-away (frangible) structures within the OFZ. Airports will have to utilize the OFZ in order to upgrade landing systems. This paper describes analytical procedures used in the development of a frangible fiberglass antenna tower. The tower was assumed to act as a truss and therefore, the transversely isotropic nature of the fiberglass did not have to be accounted for. A simplified linear static finite element procedure was performed and it verified that the tower will withstand environmental loading. A dynamic analysis was performed to model the event of an aircraft impact and verified that failure would be initiated by an aircraft impact. The use of fiberglass provided a design that not only met structural requirements, but eased transport, simplified erection, and improved maintenance.
