Load effects in bridges result from single truck crossings or multiple-truck presence events which are, statistically, not identically distributed. Conventional approaches fit statistical distributions to mixtures of non-identically distributed load effects. Inaccuracies in the conventional approach are identified and an alternative approach is developed to find the characteristic load effects. Theoretical and field data is used to show the potential implications of conventional techniques and to demonstrate the application of the new approach.433739 bytesapplication/pdfenAll rights reservedBridgeAssessmentStatisticsExtreme ValueTrafficLoadWIMMixtureBridges--Live loadsStructural dynamics--Statistical methodsJournal Article30539440410.1016/j.strusafe.2006.11.006https://creativecommons.org/licenses/by-nc-sa/1.0/
