Abstract:

Fiber reinforced composite materials offer significant advantages over conventional materials for such factors as corrosion resistance, lighter weight, and higher strengths. These advantages have been exploited by many industries such as aircraft, aerospace, transportation, chemical, etc. The possible use of high strength composite cables is explored herein for a variety of bridge applications including suspension and stayed bridge cables and tendons for concrete decks. A couple of new types of end connection are presented which provide for excellent creep-relaxation and fatigue performance at working stress levels equivalent to high strength steel tendons.
