Abstract:Roadside signs on Florida highways must fulfill two seemingly conflicting structural roles. First,
they must withstand hurricane-force winds, and second, they must be able to breakaway when struck by a vehicle. The breakaway requirement is intended to reduce the hazardous, sudden deceleration that can occur when a car leaves the roadway and strikes a roadside sign. University of Florida researchers studied the use of steel, fiber-reinforced polymer (FRP), and steel/FRP components in breakaway devices for roadside signs. The researchers used the pendulum impact test facility at the Florida Department of Transportation State Structures Laboratory in Tallahassee, Florida.
