Abstract
The accurate estimation of site-specific lifetime extreme traffic load effects is an important element
in the cost-effective assessment of bridges. 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.
