Next-Generation Wireless Bridge Weigh-in-Motion (WIM) System Integrated with Nondestructive Evaluation (NDE) Capability for Transportation Infrastructure Safety

• The main goal of current research work is on simulation of heavy vehicle to bridge interaction using advanced finite element modeling technique in order for effective use with the moving force identification (MFI) algorithm for the B-WIM system for enforcement and safety assessments. For this reason, the 3D heavy vehicle model was created with a complex suspension and damping system along with pneumatic tires. In addition to this, the 3D bridge model was developed with different types of elements such as beam, shell and solid. Transient dynamic vehicle to bridge interaction analysis was carried out based on numerical finite element computational mechanics using LSDYNA advanced computer program. We are in the process of mapping the 3D LSDYNA output of bridge-vehicle interaction analyses onto recently developed MFI algorithm from this current project. Our recently developed MFI algorithm is not, however, capable of integrating high fidelity simulation output from 3D LS DYNA. So significant efforts are currently underway on upgrading MFI algorithm and implementing the approach on a US-78 bridge.
