Experimental Study on Flexural Behavior of CFRP Bar Reinforced Concrete Bridge Deck with Corrosion and Salt Resistance

Abstract:

In order to improve bridges durability, this paper designed a kind of bridge deck with carbon fiber reinforced polymer (CFRP) bar reinforced concrete deck, which is salt and corrosion resistant. Through model test, the relationship between load and displacement, ultimate flexural capacity, stress distribution of CFRP bars, concrete strain distribution of the new bridge deck with different CFRP ratio was investigated. New bridge decks present characteristics of partial plastic failure, has similar structure strain trends and stress distribution compared with steel reinforced concrete decks, and accord with plane section assumption. The bond force, between CFRP bar and concrete, controll the flexural capacity of new bridge decks.
