Flexible column viscous spring damper

The Journal of the Acoustical Society of America, 1986
A viscous spring damper for damping and levelling structural agitation comprising a first outer member joined to a connecting member by a first elastomeric shear spring, the first outer member including a first fluid chamber and a first elastomeric diaphragm.

Seismic performance evaluation of a spring viscous damper cable system

Engineering structures, 2018
This research proposes a self-centering passive damping system consisting of a spring viscous damper linked with a preloaded tendon. The seismic performance of the spring viscous damper is evaluated by cyclic loading tests, and the results are used for ...

Performance assessment of an earthquake-based optimally designed fluid viscous damper under blast loading

Advances in Structural Engineering, 2019
Terrorist attacks and explosion devices are one of the growing worldwide threats which seriously threaten the safety of strategic structures. The aim of this study is assessing the performance of the linear fluid viscous damper optimally designed based ...

Viscous damper development and future trends

The Structural Design of Tall Buildings, 2001
AbstractViscous dampers can protect structures against wind excitation, blast and earthquakes. Viscous damper technology originated with military and aerospace applications. Approximately 10 years ago it was found that the same fluid viscous dampers that protect missiles against nuclear attack and guard submarines against near‐miss underwater ...

Comparing fluid viscous damper placement methods considering total‐building seismic performance

Earthquake engineering & structural dynamics (Print), 2018
Nonstructural damage has been found to critically influence economic losses and building downtime following earthquakes. Attaining a target level of seismic performance mandates the harmonization of structural and nonstructural performance.

Mitigation of micro vibration by viscous dampers

Earthquake Engineering and Engineering Vibration, 2009
This study proposes a micro vibration mitigation system using viscous dampers to solve the problem of vibration in a high-tech building. Due to the operating frequency of the air conditioners and fundamental mode of the floors, a resonant phenomenon is occasionally experienced at the upper levels of the structure.

Effective damping and frequencies of viscous damper braced structures considering the supports flexibility

Computers & structures, 2017
This paper presents a study on the optimal sizing of damping braces of MDOF systems equipped with viscous dampers where, unlike well-established computer-based optimisation methods, the deformability of the elastic supports is integrated by means of a ...
