This paper proposes a new semi-active variable stiffness and damping system (AVSD) for vibration control of civil engineering structures. The AVSD system can alter rigidity and damping of the controlled structure at each control interval to attenuate the structural responses. The composition of two hydraulic cylinder-piston systems of the AVSD system is capable of amplifying the interstory drif...
