Bridge Traffic Loading

Eugene O’Brien is Professor of Civil Engineering at University College Dublin. He has previously worked in industry and led the study that resulted in an increase in the allowable weights of trucks in Ireland. He has worked on most aspects of Bridge Traffic Loading including Weigh-in-Motion, loading on secondary roads and loading on long-span bridges. He has pioneered new concepts such as scenario modeling, apparent permit vehicles and micro-simulation modeling for long-span bridge load calculation. Andrzej Nowak is Professor and Department Chair of Civil Engineering at Auburn University. His development of a reliability-based calibration procedure for calculation of load and resistance factors has been successfully applied to calibration of the AASHTO design code for bridges, ACI 318 Code for Concrete Buildings and Canadian Highway Bridge Design Code. He has an Honorary Doctoral Degree from Warsaw University of Technology, he is a Fellow of ASCE, ACI and IABSE, and he has received the ASCE Moisseiff Award, IFIP WG 7.5 Award, Bene Merentibus Medal, and the Kasimir Gzowski Medal from the Canadian Society of Civil Engineers. Dr Colin Caprani is a Senior Lecturer in Civil Engineering at Monash University. He has worked as a design structural engineer on a wide range of projects, including integral bridges and new-concept bridge beam development. He is an Associate Editor of the ASCE Journal of Bridge Engineering and Structural Safety.
