condition in dynamic behaviour of a straight beam under action of moving
force is investigated. Furthermore, the effectiveness of various parameters
such as beam geometry and material type on dynamic magnification factor
is studied. This study shows that maximum dynamic magnification factor
only depends on boundary condition. This value is obtained at a critical
to moving load velocity ratio that is independent of material and beam
geometry and only depends on boundary condition. The Maximum dynamic magnification
factor for composite and isotropic material in each boundary condition
is slightly different.]]>Abu-Hilal, M. and M. Mohsen,2000Anonymous,2004Fryba, L.,1999Gbadeyan, J.A. and S.T. Oni,1995Ichikawa, M., Y. Miyakawa and A. Matsuda,2000Kadivar, M.H. and S.R.
