Abstract

Through and half-through arch bridges are modern bridge types due to the development of steel as a building material, in which up to now the dead-load of the deck system and the live load are transferred to the arch rib by steel suspenders. However such suspenders are due to complex mechanical loading patterns and atmospheric attacks suffering fatigue, fretting fatigue, stress corrosion and corrosion. In the past decade, even bridge decks collapsed due to these problems. Realizing the excellent properties of carbon fiber reinforced polymers (CFRPs), including corrosion resistance, very high specific strength and stiffness, and outstanding fatigue behavior, the application of CFRPs for suspenders will be a good choice. In this paper, the bridge deck collapses due to broken steel suspenders will be reviewed, and a proposal for the application of CFRP suspenders for arch bridges will be introduced.
