Abstract

Journal of Vibration and Control, Ahead of Print.
This paper focuses on the interval dynamic response of a damaged arch with uncertain parameters under a moving load. The differential quadrature method (DQM) is employed to derive the equation of motion of the arch. The moving load, modeled as the Dirac ...
