Abstract:A new compound method of physical parameters identification of bridge structures under traffic excitation is presented in this paper. Employing the Dynamic Nodal Loading (DNL) approach, which could consider the dynamic response due to the road irregularities and vehicle inertia effect of a vehiclestructure system, the moving vehicle load could be converted into the transient load on each node in time domain. Then, the accelerate response of bridge structures calculated with the Newmark β − method, is used to c… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
