Compression Lap-Splices of FRP Bars in Reinforced Concrete Columns under Static and Cyclic Loading

Corrosion of steel bars stands out as a significant factor limiting the life expectancy of reinforced-concrete infrastructure exposed to harsh environmental conditions. In the last decade, the use of fiber-reinforced polymer (FRP) bars as an alternative reinforcing material in reinforced-concrete (RC) structures has emerged as an innovative solution to the corrosion problem. In the field application, it is inevitable to connect FRP bars because of limited length of bars for storage and transportation. The easiest and practical method to connect FRP bars is over lap splicing. The critical parameter affecting strength of spliced bars is over lap splice length. The main aim of this project is to develop an equation to calculate splice length of FRP bars. The outcomes of this project promote utilization of this new material in construction industry and extend the life expectancy of infrastructures in Canada and consequently decrease the infrastructure maintenance cost.
