Viscous DAMPERS : Practical Application Issues for the Structural
Only in recent years have fluid viscous dampers (FVDs) been incorporated into building designs and retrofits in the United States to control the seismic and wind response of structures. They have been found to be an effective way of introducing damping to a structure to decrease building displacements. However, in Japan and several other countries, the FVD technology has been incorporated into ...
متن کاملViscous + Dahl model for MR dampers characterization: A Real time hybrid test (RTHT) validation
Magnetorheological dampers have raised as promising devices for structural seismic protection since they have many attractive features such as small power requirements, reliability, and relatively low cost. These devices have strongly nonlinear behaviour which is very difficult to characterize. For this reason, the modelling of MR dampers has been an active field during the last years and has p...
متن کاملEquivalent Damping Ratios of Structures with Supplemental Viscous Dampers
The current design formulas such as those provided by FEMA273/274 for building structures with supplemental viscous dampers were derived based on the shear building assumption. However, for medium-rise to high-rise buildings that deform in a combined form of shear and bending when subjected to seismic loading, the design using existing formulas may result into an actual damping ratio much lower...
متن کاملAn assessment of a semi analytical AG method for solving two-dimension nonlinear viscous flow
In this investigation, attempts have been made to solve two-dimension nonlinear viscous flow between slowly expanding or contracting walls with weak permeability by utilizing a semi analytical Akbari Ganji's Method (AGM). As regard to previous papers, solving of nonlinear equations is difficult and the results are not accurate. This new approach is emerged after comparing the achieved solutions...
متن کاملAnalytical assessment of reinforced concrete frames equipped with TADAS dampers
In recent years, it is considerably attempted to develop the concept of energy dissipation as an applicable technology to overcome the energy released by earthquakes. The passive control systems such as metallic dampers have been widely considered. The dampers are basically used to mitigate the structural responses and reduce the damages in main structural elements by energy dissipation. ...
