“…However, the parameters that define this effectiveness can vary and, depending on the type of structure, one can use displacement values, inter-story drifts, internal force values or accelerations [369]. Consequently, different optimization strategies and different objective functions are adopted [370]: maximum inter-story drifts, the sum of inter-story drifts [371][372][373], absolute acceleration [374], displacement [374,375], base shear [374], an energy-based damage index [376], and base moments [377], as well as the combinations of some structural performance functions; see Figure 8. In the approach involving an incremental formulation of the inverse problem (I the amplitude of the transfer function expressed as the sum of inter-story drifts a fundamental natural frequency can be minimized with a reduction in the total amou damping [370,372].…”

“…In the approach involving an incremental formulation of the inverse problem (IPA), the amplitude of the transfer function expressed as the sum of inter-story drifts at the fundamental natural frequency can be minimized with a reduction in the total amount of damping [370,372]. The advantage of this approach is that the algorithm is simple and the result obtained is independent of the input ground motions [383].…”

The paper is devoted to a review of recent achievements in the field of dynamic analysis of structures and structural elements, such as beams and plates, with embedded viscoelastic (VE) dampers and/or layers. The general characteristics of VE materials, their rheological models, and methods of parameters identification are discussed. New formulations of dynamic problems for systems with VE elements are also reviewed. The methods of determination of dynamic characteristics, together with the methods of analysis of steady-state and transient vibrations of such systems, are also discussed. Both linear and geometrically non-linear vibrations are considered. The paper ends with a review of the methods of sensitivity and uncertainty analysis, and the methods of optimization, for structures with VE elements.
