Abstract

In most bridge design codes, the current design approach for concrete bridge deck slabs assumes a flexural behaviour under concentrated wheel loads. However, the carrying capacity of bridge deck slabs with depth-to-span ratio of up to 15 is greatly enhanced due to the formation of arching action developed by lateral restraints. This paper presents results of non-linear finite element Model (FEM) to predict the behaviour of concrete bridge deck slabs reinforced with FRP bars under service and ultimate limit states. The validity and accuracy of the non-linear finite element analysis were verified against experimental test results conducted by the authors. The experimental work included the construction and testing of 2 full size concrete deck slabs (3000-mm long × 2500-mm wide × 200-mm deep). One slab was reinforced with glass FRP and the other slab was reinforced with carbon FRP bars. Using the FEM, the behaviour of the FRP-reinforced bridge decks with different reinforcement ratios was evaluated.
