Assessment of serviceability limit state of vibrations in the UHPFRC-Wild bridge through an updated FEM using vehicle-bridge interaction
The serviceability limit state of vibrations of the UHPFRC-Wild bridge is assessed. An iterative method based on the genetic algorithm is developed to update the FEM of Wild bridge. A vehicle-bridge interaction model is proposed, using the multibody system with the finite element model. A complete road surface roughness is generated based on the PSD and on the isotropy hypothesis. Congested traffic flow is considered to analyze the influence of traffic.
