	Summary:
	Dynamics of a structure consisting of two rigid blocks positioned one on another with a viscoelastic and a friction damper is analyzed. Due to a horizontal ground excitation the viscoelastic plate is exposed to a shear loading. The fractional Zener model is used to describe properties of the viscoelastic body while the friction damper is modelled by the Coulomb friction law in a set-valued form. The horizontal ground motion is described by a simplified earthquake model by means of Ricker's waves.
