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.
