Cyclic engagement of hysteretic steel dampers in braced buildings: a parametric investigation [PDF]

Bulletin of Earthquake Engineering, 2021
Hysteretic steel dampers have been effectively used to improve the seismic performance of framed buildings by confining the dissipation of seismic energy into sacrifical, replaceable devices which are not part of the gravity framing system. The number of

Seismic performance and damage evaluation of a reinforced concrete frame with hysteretic dampers through shake‐table tests [PDF]

Earthquake Engineering and Structural Dynamics, 2014
Passive energy dissipation devices are increasingly implemented in frame structures to improve their performance under seismic loading. Most guidelines for designing this type of system retain the requirements applicable to frames without dampers, and ...

Optimum strength ratio of hysteretic damper

Earthquake Engineering & Structural Dynamics, 1998
An accurate and practical testing technique to study seismic performance of multi-storey infilled frames is formulated. This technique is based on the pseudo-dynamic method which can provide an acceptable approximation of the dynamic performance of structures under the influence of earthquake excitation.

Hysteretic Properties of Shell Dampers

2018
The achievements of the authors in the analytical modeling of hysteretic energy dissipation in the systems of shells with deformable filler at the expense of dry friction are presented. Four design variants are considered: solid shell with filler, cut shell with filler and the same systems with internal coaxial shell.

Hysteretic dampers for earthquake‐resistant structures

Earthquake Engineering & Structural Dynamics, 1974
AbstractThe earthquake resistance of many structures can be increased by the inclusion of special components which act as hysteretic dampers. During moderately severe earthquakes these dampers act as stiff members which reduce structural deformations, while during very severe earthquakes the dampers act as energy absorbers which limit the quasi ...

Modeling asymmetric hysteretic properties of an MR fluids damper

2004 43rd IEEE Conference on Decision and Control (CDC) (IEEE Cat. No.04CH37601), 2004
A generalized model is synthesized to characterize the asymmetric hysteretic force-velocity properties of a magneto-rheological (MR) fluid damper as a function of the command current, excitation frequency and displacement amplitude, on the basis of symmetric and asymmetric sigmoid functions.

Hysteretic Model of Stiffened Shear Panel Dampers

Journal of Structural Engineering, 2006
A properly designed two-way stiffened (stiffened both in longitudinal and transverse directions) shear panel can sustain large deformation without pinching and consequent strength degradation. Hence it can be used as an effective passive energy dissipating damper (PEDD) in building and bridge structures to absorb seismic energy. In this Technical Note,

Rehabilitation of existing masonry structures with hysteretic dampers

2014
A displacement-based method for the design of an energy dissipating system is herein proposed. The device, which is composed of added concrete walls equipped with hysteretic Added Damping and Stiffness dampers, is aimed at upgrading the seismic behaviour of existing masonry structures.
