In this paper an inertial amplification mechanisms with an embedded  smart spring-damper device for attenuation of bending vibrations in continues structures are analyzed. The complex systems are the extension of the already investigated inertial mechanism , here additionally equipped with the vacuum controlled  spring-damper device which shows features of smart materials. This allows the semi-active control to affect different frequency ranges of the vibration in the real time. The features of the basic inertia amplification mechanism are preserved as a possibility to generate two neighboring  anti-resonance frequencies between resonance peaks in the low frequency range. The authors show different approaches to their concepts and research from the earliest solutions  to the final design.
