Fluid Dynamics and Behavior of Nonlinear Viscous Fluid Dampers
Journal of Structural Engineering, 2008Fluid dynamics in viscous fluid dampers with annular orifices was analyzed by solving the Navier–Stokes equations. The shear-thinning effect and viscoelastic behavior of silicone oil, which is often used in a viscous fluid damper, were both considered.

Intensity-Reduced Design for Structure with Fluid Viscous Dampers
Applied Mechanics and Materials, 2014The intensity-reduced method based on fluid viscous dampers is proposed in this study. The analysis model of fluid viscous dampers is firstly introduced. The intensity-reduced design procedure is thoroughly discussed. Taking an 11-story reinforced concrete frame shear-wall structure as example, the intensity-reduced method is implemented in this study.

Special Fluid Viscous Dampers For The Messina Strait Bridge
AIP Conference Proceedings, 2008The Messina Strait Bridge would be the world's longest suspension bridge, with a design earthquake characterised by a PGA value of 0.58 g and a distance between the ipocenter and the bridge of 15 km. Said critical structure of course would need a suitable restraint system for traffic braking loads, wind and seismic actions. Each type of load requires a

Analysis of high-rise building by using fluid viscous dampers
i-manager's Journal on Structural Engineering, 2022Fluid viscous dampers are dynamic actuators that when stroke, it absorb the energy that by tectonic disturbances, wind absorption, or heat on a structure. Every multi-story building structure that is subjected to ground motion in daily life needs to be studied to determine how it responds because this is a common issue for construction. The structure's

Investigation of Impulse Response of an ER Fluid Viscous Damper
Journal of Intelligent Material Systems and Structures, 2009The electrorheological (ER) fluid is a fluid that shows non-Newtonian fluid characteristics when the electrical field is applied. In this study, an experiment of an ER fluid viscous damper, in which an ER fluid is enclosed in the gap of a piston—cylinder system, is carried out to investigate the performances of the ER fluids and the effects of the ...

Viscous Heating of Fluid Dampers. II: Large-Amplitude Motions
Journal of Engineering Mechanics, 1998In this paper, the problem of viscous heating of passive and controllable fluid dampers is analyzed at the limit of long-stroke motions, where most of the fluid travels through the damper orifice(s) or valve(s). This study is of interest in the case of strong earthquake motions where dampers are subjected to long-stroke motions.

Seismic Behavior of Wood‐framed Structures with Viscous Fluid Dampers
Earthquake Spectra, 2004The suitability of viscous fluid dampers for seismic protection of light‐framed wood buildings is investigated in this paper. Nonlinear finite‐element models of wood building components (shear wall) and systems (three‐dimensional buildings) are developed and numerical analyses are performed to evaluate their response to seismic loading.

Reliability of a r.c. frame equipped with linear and nonlinear fluid viscous dampers
2019Retrofit interventions with Fluid Viscous Dampers (FVDs) are efficient to reduce the vulnerability of existing buildings. In particular, external dissipative system based on FVDs are very promising since they present some feasibility advantages with respect to more classic solutions involving devices installed within the existing frames.
