When assessing the total traffic load effect on a bridge, there is a number of alternatives to characterise the associated dynamic component depending on the information available to the engineer. The simplest approach is to adopt the conservative values provided in bridge codes covering for many uncertainties. Nevertheless, if bridge drawings, bridge properties, updated weigh-in-motion data and road profile were known, then validated vehicle-bridge finite element interaction models can be used to reduce these uncertainties. Dynamic allowance can also be experimentally derived from measured total load effects using modern bridge weigh-in-motion technology. Guidelines are provided on how to obtain a site-specific value of dynamic allowance, both numerically and experimentally.||Type of material:||Conference Publication||Publisher:||CRC Press||Copyright (published version):||2012, Taylor and Francis Group||Keywords:||Bridge loads;Bridge assessment||Language:||en||Status of Item:||Not peer reviewed||Is part of:||Franogpol, D.
