Title: Implementation of Closed GFRP Stirrups in FRP-RC Design of Traffic Barriers
Author(s): Paolo Rocchetti, Guillermo Claure, Francisco De Caso, and Antonio Nanni

Abstract:The aim of this project is to develop the necessary design knowledge to implement GFRP reinforcement in concrete traffic barriers. Innovation lies in the use of GFRP closed continuous stirrups that became recently available. The design method relies on AASHTO-LRFD Bridge Design Specification and the latest development in specifications issued by the Florida Department of Transportation (FDOT) for Reinforced Concrete (RC) Traffic Barriers. After a review of design procedures for traffic barriers and understanding the mechanical characteristics of GFRP reinforcement, a modified design approach is proposed to reduce GFRP reinforcement amounts and complexity in construction. Supported on experience gained from designing FDOT 32” F–Shape (F32) GFRP RC used in the Halls River Bridge Replacement Project, this study also addressed the 36”–Single Slope (SS36) traffic barrier to be adopted by FDOT in coming years.
