Abstract: Traffic loading crossing a bridge is simulated to analyse the correlation between the worst static and dynamic load case. The worst static cases are obtained through a Monte-Carlo simulation using weigh-in-motion (WIM) data from a typical European route. The bridge model is a twolane 20 m long single span structure discretised into plate elements. The truck model is composed of bar, mass, damping, spring and rigid elements. The road profile is generated stochastically from power spectral density functions. The dynamic interaction between bridge, truck and road profile is solved using a Lagrange multiplier technique. Dynamic amplification factors are obtained for the critical static loading cases, which for a two-lane 20-m bridge is due to meeting events between two five-axle trucks. Results are compared to the Eurocode recommendations.
