  • Friction type retrofitting device for steel tower structures
    Publication number: 20080092478
    Abstract: Disclosed herein is a friction type retrofitting device for steel tower structures. The retrofitting device includes a coupling part which couples an outer column and an inner column of a post of a steel tower to each other using an angle bracket and a bolt. A slot is formed in a portion of the outer column to which the coupling part is coupled. A friction plate is provided to contact an outer circumferential surface of the slot. Thereby, wind energy transmitted to the steel tower is attenuated by friction between the outer circumferential surface of the slot of the coupling part and the friction plate.
