Abstract

One of the methods for the assessment of existing bridges is to subject the bridge to a load test. What is still lacking is a reflection of these recent advances in the codes and guidelines used for load testing of bridges. Two approaches are being used to address this lack. The first approach attempts to answer fundamental questions with regard to bridge load testing, and in particular proof load testing of concrete bridges through research. The second approach is to coordinate efforts, and facilitate collaboration and exchange of ideas internationally through the creation of the IABMAS Technical Committee on Bridge Load Testing. It is expected that these efforts will lie at the basis of improved recommendations for the assessment of concrete bridges by load testing to be included in codes and guidelines and to serve the community of engineers faced with the increased task of assessing ageing infrastructure.
