Using diagnostic load tests for accurate load rating of typical bridges
Historically, bridge load ratings based solely on theoretical calculations tend to be overly conservative, due to the many assumptions made in the modelling of a bridge. A controlled load test can be used to determine a more accurate load rating of the bridge. An overview of typical controlled load tests is presented in this paper. Specific attention is given to determining the bridge’s actual live load distribution, assessing support fixity, unintended composite action, and contributions from non-structural components. The manner in which these factors are computed and applied directly to standard beam models currently used to load rate bridges is also discussed.
