 Summary:
 We analyzed two adjacent structures connected by a friction element to each other. Both structures consist of two blocks and a viscoelastic damper, which is modeled by the fractional Zener model. The friction force within the friction element is described by the Coulomb friction law in a set-valued form. Horizontal ground motion induces movement of both structures which can cause a destroying pounding effect. Energy brought to the system consisting of two structures connected by a friction damper dissipates by work done by viscoelastic and friction forces. Ground excitation is modeled by a simplified earthquake model by means of Ricker's waves.
