DOI: 10.1142/s0219455427710015
Abstract: To address the challenge of closely spaced modes commonly observed in multi-span or two-span bridges, variational mode decomposition is incorporated into the vehicle-scanning method to numerically extract individual bridge frequencies from the test vehicle’s acceleration… read more here.
