The Eurocode for traffic loading on long-span bridges was derived from simulations of convoys of trucks at small bumper-to-bumper distances. Real congested traffic includes a mix of cars and trucks with a variety of congestion patterns, which reduce the load effects. Micro-simulation is used in this study to generate more realistic traffic loading scenarios, based on real traffic data from a Polish site. The results are then extrapolated to determine characteristic maximum effects for two return periods. The Eurocode is shown to be conservative, and micro-simulation based assessment is therefore valuable for problem long-span bridges.||Funding Details:||European Commission - Seventh Framework Programme (FP7)||Type of material:||Conference Publication||Publisher:||CRC Press||Start page:||3420||End page:||3427||Copyright (published version):||2012 Taylor and Francis||Keywords:||Traffic; Load; Bridge; Microsimulation; Loading; Eurocode; EC1||Language:||en||Status of Item:||Peer reviewed||Is part of:||F.
