Moving Load on Visco-Elastically Supported Beam with Localized Disturbances

In this paper a finite Euler-Bernoulli beam on viscoelastic foundation subjected to moving loads is analysed. The beam and the viscoelastic foundation have uniform properties, however, it is considered that concentrated masses, springs and dampers are also parts of the structure. Masses can contribute by transverse as well as rotational inertia, springs and dampers can be linear or rotational. They will be named as localized disturbances. Ways of analytical solution based on modal expansion are reviewed. Advantages and disadvantages are discussed, regarding the computational difficulty and efficiency.
