Date of Defense 2002-08-02 Availability unrestricted AbstractWith recent advances in the area of fiber reinforced polymers (FRP), more effort has been spent trying to incorporate the use of FRP in design applications. FRP bars offer both an ultimate strength and a corrosion resistance greater than traditional steel reinforcing. Fiber reinforced polymer bars can either consist of continuous glass (GFRP), aramid (AFRP) or carbon fibers (CFRP). CFRP bars, while lighter than GFRP typically offer a much greater tensile strength.
With the recent release of the American Concrete Institute’s first edition manual ACI-440.1R “Guide for the Design and Construction of Concrete Reinforced with FRP Bars” (2001), unified design equations were finally presented. However, the document has acknowledged that equations in the area of development lengths, splices and other details were still conservative due to the limited data available.
The objective of this research is to predict the performance of concrete beams reinforced with spliced CFRP bars of different lap splice lengths in the tension zone. This is to be done by evaluating experimental data and comparing against theoretical values. Conclusions drawn from this analysis are to be used to further refine the design equation for splice lengths.
