Metallic Yielding Dampers and Fluid Viscous Dampers for Vibration Control in Civil Engineering: A Review

Abstract

Structural vibration is a widespread issue occurred in the field of civil engineering. The passive energy dissipation devices are being increasingly popular for protecting structures from external excitations due to their high performance and no need for external energy. They can be divided into displacement-dependent dampers and velocity-dependent dampers, among which the metallic yielding dampers (MYDs) and fluid viscous dampers (FVDs) are the most representative. This paper presents an overview of the MYD and FVD, aiming to reveal their defects and provide suggestions for future development. The basic concept, the mechanical models, the design approaches, and the applications in civil engineering of the two dampers are reviewed. In particular, the obstacles in application and preference in research of these two dampers are summarized, and their merits and drawbacks are further discussed. Emphatically, the strategies for improvement and future development trends are explored.

Current Trends in Fluid Viscous Dampers with Semi-Active and Adaptive Behavior

“…In many applications, FVDs are encased in bracing systems, and a reliable mathematical model should also include the stiffness of the brace [74,75]. To this scope, different models were developed [31,71,76,77], and the Kelvin-Voigt model [78] as well as the Maxwell model [44,79] are the ones most largely adopted and implemented in the principal Finite Element Method (FEM) software programs, such as MidasGen 2023 [80] and SAP2000 v25.0.0 [81]. Between them, the Maxwell model is more common because it is more accurate when representing the viscous damping force [74,78,82,83], as it is able to capture the relaxation time of FVDs [74,83,84].…”

“…where 𝑥 , 𝑥 , 𝑥 and 𝑥 , 𝑥 , 𝑥 are, respectively, the displacement and the velocity of the dashpot (𝑥 , 𝑥 ), of the spring (𝑥 , 𝑥 ), and their combination (𝑥, 𝑥 ) [44]. 𝐾 in Equation ( 3) is the stiffness of an equivalent spring that includes both the stiffness of the bracing system and the inherent stiffness of the FVD [75].…”

“…The state of the art of seismic protective systems based on energy dissipation has been the subject of several reviews [13,14,40,[44][45][46]. Hu et al [44] conducted a review on passive Metallic Yielding Dampers and Fluid Viscous Dampers (FVDs); Spencer and Nagarajaiah [40], Symans and Constantinou [14], and Xu et al [46] focused their research on semi-active devices only, while Soong and Spencer [45] presented a study on active, semi-active, and hybrid devices. An updated review of the technological development of FVDs, with a particular focus on semi-active dampers with adaptive behavior, is the subject of the present paper.…”

Parametric optimization of the Eddy current dampers applied to a suspension bridge considering bi-directional earthquakes

“…To improve the seismic performance of longspan bridges, passive control devices were proposed and became increasingly attractive in both longitudinal and transverse directions (Lavassani et al, 2020;Martínez-Rodrigo and Filiatrault, 2015). They can provide supplemental energy consumption and damping to the bridge, diminishing the structural responses and reducing the damage (Cui et al, 2018(Cui et al, , 2023Hu et al, 2022a;Konar and Ghosh, 2022).…”

An Unconditionally Stable Integration Method for Structural Nonlinear Dynamic Problems

“…With the continuous development of viscous damping materials, viscoelastic materials, and metallic materials, more and more new types of dampers with greater energy dissipation capacity and deformation capacity have emerged [1][2][3]. The complexity of structural nonlinearities is heightened by the incorporation of diverse types of dampers [4,5].…”
