NUMERICAL INVESTIGATION OF STRUCTURAL BEHAVIOUR OF SCC DECK SLABS REINFORCED WITH BFRP BARS
The use of self-compacting concrete(SCC)reinforced with fiber-reinforced polymer(FRP)bars is anticipated to address the concerns on the usage of traditional reinforced concrete structures,such as corrosion of internal steel reinforcement,costly repair and development to low-energy infrastructure.This paper reveals a numerical investigation of the behaviour of BFRP reinforced SCC deck slabs in a real bridge,Thompson Bridge in Nothern Ireland,U.K.A nonlienar finite element model was proposed by using ABAQUS 6.10 in this study.The results of the field test in Thompson Bridge were used to access the accuracy of finite element model.The proposed nuermcial model showed a good correlation with the test results.Thereafter,this numerical model was adopted to study the ultmate behaviour of the BFRP reinforced SCC bridge deck slabs with a series of parametric study.It was found that the SCC with BFRP rebar provided an similar ultmate behaviour compared with steel reinforced concrete.The BFRP reinforcement bar provides an alternative corrosion-resistant system,which has substantially improved whole-life performance compared with corrosive steel reinforcement bar.
