Venkatesh Kodur (Michigan State University, USA)
Dr. Venkatesh Kodur is a University Distinguished Professor in the Department of Civil and Environmental Engineering at Michigan State University (MSU). He also serves as Director of the Centre on Structural Fire Engineering and Diagnostics at MSU. His research interests include: Evaluation of fire resistance of structural systems through large scale fire experiments and numerical modeling and Characterization of materials under high temperature. His research contributions has lead to the development of fundamental understanding on the fire behavior of material and structural systems and also resulted in numerous design approaches and innovative and cost-effective solutions for enhancing fire-resistance of structural systems. He has published over 400 peer-reviewed papers in journals and conferences, and has given numerous invited key-note presentations. He is one of the highly cited authors in Civil Engineering and as per Google Scholar, he has more than 9200 citations with an "h” index of 54. The methodologies, techniques and design guidelines, resulting from his research, have been incorporated in to various codes and standards, as well practical applications, in the US and around the world and are instrumental in minimizing the destructive impact of fire in the built infrastructure.
Prof. Kodur is a Fellow of the Canadian Academy of Engineering and a Foreign Fellow of Indian National Academy of Engineering. He is a professional engineer, Fellow of American Society of Civil Engineers, Fellow of Structural Engineering Institute, Society of Civil Engineers, Fellow of American Concrete Institute, Associate Editor of Journal of Structural Engineering, Past Chairman of ACI Fire Protection Committee, Chairman of ASCE-29 (Fire) Standards Committee and a member of UK-EPSRC College of Reviewers. He has won many awards including MSU University Distinguished Professor, American Institute of Steel Construction Faculty Fellowship Award, MSU Distinguished Faculty Award, NRCC (Government of Canada) Outstanding Achievement Award and NATO Award for collaborative research. Dr. Kodur was part of the FEMA/ASCE Building Performance Assessment Team that studied the collapse of WTC buildings as a result of September 11 incidents.
Strategies for Mitigating Fire Hazard in Steel Bridges
Fire is one of the most severe environmental hazards to which the built infrastructure may be subjected during its lifetime. In recent years, due to rapid development of urban ground-transportation systems, as well as increasing transportation of hazardous materials, bridge fires have become a growing concern. Bridge fires can lead to significant economic and public losses; however, no specific fire resistance provisions are specified for bridges in AASHTO, NFPA, and other standards. This is contrary to structural members in buildings where adequate fire resistance provisions are to be provided to maintain structural stability and integrity in the event of a fire.
In the presentation, an approach, in the form of importance factor, will be proposed for classification of bridges based on fire risk. Detailed results from fire resistance experiments and numerical studies carried out to evaluate fire resistance of steel bridges will be presented. A series of design strategies to enhance fire safety of critical bridges will be presented. These strategies range from utilizing inherent fire resistance in structural members, through advanced analysis approaches, to providing some level of fire protection (insulation) to vulnerable components of steel bridges. Applicability of proposed strategies to practical situations will be demonstrated through case studies on different steel bridges that experienced fires in recent years.
