Abstract:

A microwave tower in Florida was built of cast-in-place concrete instead of steel, because: (1)Concrete was considered more esthetic than steel; and (2)concrete was more resistant than steel to salt air, thereby reducing maintenance. Although the concrete tower cost about twice as much as a comparable steel tower, the difference is expected to be more than offset by reduced maintenance costs. Designed to resist 180-mph hurricane winds, the tower is 170-ft tall, is 18-ft square and has a 4.5-ft-thick concrete foundation extending 35-ft from the tower center. Two 13-ft by 31-ft concrete boxes in the tower house two pairs of antenna horns, and the tower includes provision for two more pairs in the future. The designer won two awards from Florida associations for the tower.
