A ROBUST SOLUTION TO STRENGTHENING RC AND PC BEAMS

All UK road bridges must be capable of carrying 40 tonne vehicles by 1999. Many have been found to be inadequate and the authors discuss the use of both pultruded and pre-preg carbon and glass fibre reinforced polymer materials as an alternative to the existing steel plate bonding used to strengthen reinforced or pre-stressed concrete bridges. The ROBUST (stRengthening Of Bridges Using polymeric compoSite maTerials) project was designed to develop materials, applications, carry out testing and validation against models, assess durability, creep and failure and produce design standards. The polymer composites described have a high strength with better fatigue properties than those of steel and high resistance to the corrosive effects of acids, alkali salts and aggressive materials. Composites can also be designed to fit the required shape and specification. Although material costs are greater than steel, considerable savings could be made in installation and maintenance costs.
