This study presents a multilayered shear deformable beam element for dynamic analysis of laminated composite beams subjected to moving loads. The present laminated beam element includes separate rotational degrees of freedom for each lamina while it does not require any additional axial and transversal degrees of freedom beyond those necessary for a single lamina. The shape functions are selected to ensure compatibility and continuity between the laminae. Interfacial slip and delamination are not allowed. Comparisons with results available in the literature are presented to demonstrate the accuracy of the model. Results are also given for moving load-induced vibrations of laminated composite beams. Effects of the load speed, boundary conditions, and laminate lay-up on the beam response is studied.
