In this paper， an accurate and elective solution for a circular curved beam subjected to a moving load is.Proposed， which incorporates the dynamic stones matrix into the Lap lace transform technique. In the Lap lace.Domain， the dynamic stones matrix and equivalent nodal force vector for a moving load are explicitly.Formulated based on the general closed-form solution of the deferential equations for a circular curved beam.Subjected to a moving load. A comparison with the modal superposition solution for the case of a simply.Supported curved beam contras the high accuracy and applicability of the proposed solution. The internal.Reactions at any desired location can easily be obtained with high accuracy using the proposed solution， while.A large number of elements are usually required for using the _niter element method. Furthermore， the jump
Behaviors of the shear force due to passage of the load is clearly described by the present solution without.The Gibb's phenomenon， which cannot be achieved by the modal superposition solution. Finally， the present.Solution is employed to study the dynamic behaviors of circular curved beams subjected to a moving load
Considering the ejects of the loading characteristics， including the moving speed and excitation frequency， and.The ejects of the characteristics of curved beams such as the radius of curvature， number of spans， opening.Angles and damping. The impact factors for displacement and internal reactions are presented. Copyright.
