Abstract:

In this study, the impact of boundary 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.
