In this paper semi active control of seismic vibrations of structures equipped with smart frictional dampers is studied . In order to control the frictional resistance force at the sliding surface of the dampers the piezoelectric materials are used . the piezoelectric materials provide the adjusting on-surface normal force by actuation
