Southview Bridge Rehabilitation in Rolla, MO. Volume I: Design and Construction
A research project was undertaken to evaluate the use of post-tensioned Fiber Reinforced Polymers (FRP) for bridge-deck construction. The type of structure selected for this project is a four-span continuous concrete slab having Glass FRP (GFRP) bars for top and bottom mats and Carbon FRP (CFRP) reinforcement for internal post-tensioning of the bridge deck. This bridge is located in Rolla, Missouri (Southview Drive on Carter Creek). One lane of the bridge was already built using a conventional four-cell steel reinforced concrete box culvert. One lane and sidewalk needed to be added. This additional lane was constructed using FRP bars as internal reinforcement. The combination of prestressed and non-prestressed FRP reinforcement resulted in an economical solution for a deck system with low deflection and high shear strength at a minimum deck thickness. This study includes the design of the FRP portion of the bridge using existing codes when appropriate, the validation of the FRP technology through a pre-construction investigation conducted on two specimens representing a deck strip, construction and field evaluation through load testing of the bridge. The results showed how FRP, in the form of GFRP as passive and CFRP bars as active internal reinforcement, could be feasible solution replacing the steel reinforcement of concrete slab bridges, and specifically the enhanced shear capacity of the slab due to the CFRP prestressing.
