In this paper,the effect of the Lumped Mass Matrices(LMM)on the dynamic response of beams under uniformly distributed moving loads is investigated.The analysis was done by using finite element method.In this study,material properties,throughout the length of the beams under consideration are assumed to be homogeneous.The elements stiffness,mass and centripetal acceleration matrices as well as the load vectors were derived by applying the Galerkin's Weighted Residual Method(GWRM).Newmark' s integration method is used to obtain the dynamic response of beams under uniformly distributed moving loads.
