Extending the lifetime of existing concrete infrastructure

The strength enhancement of structurally deficient concrete infrastructure is an application of considerable economic and strategic importance, particularly in the case of bridges. In the United Kingdom alone, it has been estimated that there are approximately 10,000 bridges on the strategic road network and 150,000 bridges on local roads, of which a considerable number need strengthening or replacement. The estimated cost of assessing and strengthening such structures is in excess of £4 billion. Other countries, e.g. the United States, are faced with the same challenge, so emphasising the global significance of the issue.

During the past two decades, fibre reinforced polymer (FRP) reinforcement has gained acceptance as strengthening systems for existing reinforced concrete (RC) structures. The use of FRP strengthening systems is advantageous due to their excellent mechanical and durability properties. Extensive research has resulted in approved FRP flexural strengthening methods for RC structures. In contrast, FRP shear strengthening of RC structures is not yet fully understood.

We are looking for outstanding Doctoral Researchers with exceptionally strong relevant academic background to investigate, experimentally and numerically, new techniques for shear strengthening of existing concrete infrastructure. This is a demanding research project with strong potential for real life applications. Successful candidates must demonstrate enthusiasm, can-do attitude and strong skills in physical testing and/or nonlinear finite element analysis of concrete structures. Preference will be given to applicants with relevant track record of research, including journal publications.

Informal enquires may be sent to Dr Samir Dirar ([Email Address Removed]) and should contain a one-page CV.
