Abstract

En 中文

• WIM-based stochastic traffic model captures time-varying heavy vehicle flow. • Vehicle-bridge coupled analysis identifies short hangers as key warning members. • Kriging surrogate model enables rapid prediction of structural risk indices. • New framework provides exceedance probabilities for real-time bridge warning.
