Transportation infrastructure authorities worldwide are facing a huge challenge every day trying to maintain, upgrade to modern day needs, and prolong the life of existing structures. Fibrwrap Rehabilitation Systems (FRS®) are implemented in transportation infrastructure projects (bridges, tunnels, viaducts etc.) throughout the world since 1988.
Fibrwrap provides, through the implementation of TRS®, the ability to rehabilitate, repair, seismically upgrade and enhance the structural capacity of existing structures (bridges, viaducts, tunnels, retaining walls). Also, it completely satisfies the demands for structural preservation, corrosion related repair and rehabilitation, additional loading, and environmental protection. Apart from satisfying a wide range of requirements and demands, the client also benefits due to the fact that all applications can be carried out with minimum disturbance to traffic and normal every day procedures.
The FRS® can be used to enhance the structural capacity of column, girders, piers and decks of existing transportation structures, hence covering the requirements for additional strength, repair, and rehabilitation. Fibrwrap carried out the first composite retrofit of bridge columns in the United States. This was possible because in the 1980’s, the very first research program conducted on the FRS® was on bridge columns for added strength and confinement. These tests were quite successful and they led to the development of design procedures for various structural elements such as columns, beams/pier caps, walls, slabs/soffits and beam-column connections.
Significant advantages of the FRS® include: rehabilitation of corroded or distressed members, prolongation of service life, seismic retrofit of structures, increased load capacity, emergency repairs, minimum disruption of operational status (traffic) and architecturally-friendly solutions for aesthetics of structures.
