Carbon fibre composites for repair and upgrade of metallic structures. Dr. Stuart Moy University of Southampton Advanced composites are widely used for the repair and upgrade of concrete structures and the Concrete Society has published a Design Guide based on research and practical experience. Carbon fibre composites (CFRP) are now being used on the very large number of metallic structures which need strengthening and Thomas Telford has recently published a Design Guide based on two large research projects and practical application within the London Underground system. My presentation will describe the materials which make up carbon fibre composites, will give physical properties (including the play off between strength and stiffness) and will compare advanced composites with conventional materials. It will continue by explaining the methods available for applying CFRP to metallic structures including a discussion of advantages and disadvantages. The next section will look briefly at the design process and will look at long term behaviour and fire resistance. The presentation will conclude by looking at three case studies of the application of CFRP to metallic structures. These will consider the strengthening of tunnel supports, the upgrade of cast iron struts and the strengthening of a steel bridge against fatigue. Developments in Bridge Aerodynamics Dr T.A. Wyatt, Imperial College The Highways Agency in association with the Scottish Executive Development Department has just launched a revised version (BD 49/01) of the Design Rules for Aerodynamic Effects on Bridges. The presentation will combine a broad introduction to the basis of the provisions of BD 49 with indication of the principal changes in the revision. The 25-years reign of Humber Bridge as the world’s longest span having come to an end, new concepts have emerged for long span bridges. Although there is no early prospect for very long spans in Britain, British designers are strong contenders and some recent bridges and current proposals will also be illustrated. Steel Fibre Concrete Professor Ben Barr, University of Cardiff The presentation will report on the conclusions drawn at the completion of a three year contract (funded by the European Community under the Industrial and Materials Technologies Programme) entitled "Test and Design methods for steel fibre reinforced concrete (Design of SFRC"). The main objectives of the contract were to: 1. Develop test methods to evaluate the toughness of SFRC materials. 2. Develop design methods suitable for evaluating the structural behaviour of SFRC members. 3. Validate the testing and design methods through testing of large-scale SFRC specimens. The main thrust of the presentation will be a review of a round robin test programme carried out on a beam-bending test and a uni-axial tensile test recommended by a RILEM Technical Committee. The presentation will also report on tests carried out on SFRC
