This paper is concerned with the dynamic responses for structures subject to a moving load. For complex structures, the whole structure is divided into substructures to decrease the computational loads of the dynamic analysis, and the mode synthesis method is applied to the substructures to analyze the complex structure. The dynamic responses of the structures subject to moving loads are obtained using the proposed mode synthsis method, in which the component mode synthesis (CMS) method and unconstrained mode synthesis method are combined as a mixed form. The transverse vibrations of beams when a vehicle moves on non-uniform beams are treated as a model example. The computed results are compared with the experimental results, and the effectiveness of the proposed method is verified.
