In recent years, the improved quality and increasing use of weigh-in-motion technology has resulted in better quality and larger databases of vehicle weights. This has enabled measurements of the regular occurrence of extremely heavy vehicles, with weights in excess of 100 t. The collected measurements have been used as the basis for building and calibrating a Monte Carlo simulation model for bridge loading. The computer programs written to implement this model generate simulated traffic in two lanes – for both the same direction and the bidirectional cases – and calculate load effects for bridges of various spans. The research focuses on free-flowing traffic on short to medium-span bridges. This paper summarizes recent advances and their contribution to the highway bridge traffic loading problem.||Type of material:||Conference Publication||Publisher:||CRC Press||Copyright (published version):||2011, Taylor and Francis Group||Keywords:||Bridge loads; Monte Carlo simulation||Language:||en||Status of Item:||Not peer reviewed||Is part of:||Faber, M. et al.
