Speech Title: Dynamic Interactions between Vehicles and Bridge: Examples for Concrete and Steel Bridges
Abstract: This presentation regards the dynamic interactions between vehicles and bridge. 3D coupled models to simulate vehicle-bridge interaction (VBI) for estimating its structural responses and impact factors (IMs) will be discussed. By structural health monitoring (SHM), with building information modelling (BIM) of a real bridge, several data can be collected to calibrate the finite element model (FEM). Modified recent analytical equations, which account for the effects of the asymmetric two-axle vehicles, were also developed for this purpose. All these types of models provide the displacements, velocities and accelerations of the bridge and vehicles. From codes and literature, it is shown that a unique IM factor is not found. Also, most approaches underestimate the dynamic responses for bridges. Therefore, the challenge, to design modern resilient infrastructures, consists in fitting the SHM with FEM and analytical solutions to find more appropriate responses. An example for concrete and steel bridge will be shown.
