Equivalent Viscous Damping for the Elasto-Plastic Hysteretic Model [PDF]
Bulletin of the Polytechnic Institute of Jassy: Constructions, Architechture Section, 2005 The paper proposes some formulae to determine the equivalent linear parameters for spectral earthquake response of SDOF non-linear systems. The proposed formulae for the equivalent viscous damping and equivalent period are valid for the elasto-plastic ...

Dynamic behavior of steel frames: influence of material yielding and hysteretic damping mechanisms [PDF]
REM: International Engineering JournalRecent research has increasingly focused on the inelastic behavior of steel frames under severe dynamic forces, which can lead to plastic deformation, damage accumulation, and potential collapse.

Advances in Civil Engineering, 2020 In this paper, a restoring force model, composed of a trilinear skeleton curve and hysteretic rules, is proposed based on nine pseudostatic tests of the energy-dissipation joint under horizontal low cyclic loading.

Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT To enhance the structural robustness of bridges, a rocking arch‐shaped segmental pier with a double sliding system was previously proposed as a low‐cost solution to protect bridges in developing countries. The rocking behavior is triggered by halting the sliding motion, which increases the horizontal load‐bearing capacity and limits ...

Equivalent Viscous Damping Ratio Model for Flexure Critical Reinforced Concrete Columns
Advances in Civil Engineering, 2018 In order to determine the energy dissipation capacity of flexure critical reinforced concrete (RC) columns reasonably, an expression for describing the hysteretic behavior including loading and unloading characteristics of flexure critical RC columns is ...

Sensitivity of 3D Base‐Isolated Buildings to Individual Isolator Variability
Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Variability in elastomeric isolators arises from differences in rubber formulation and curing, leading to noticeable changes in stiffness and damping among nominally identical bearings. While most previous studies have examined global isolator variability associated with environmental or aging effects, individual isolator variability has ...

FOURIER ANALYSIS OF HYSTERETIC DAMPING MECHANISMS
Le Journal de Physique Colloques, 1985 A Fourier analysis of Granato-Lücke breakaway predicts amplitudes of acoustic harmonics that are comparable in order of magnitude to those observed in iron. A similar analysis of Rayleigh-law hysteresis brings out the essential differences between these two examples of hysteresis.

Earthquake Engineering &Structural Dynamics, EarlyView.ABSTRACT Viscous dampers (VDs) are widely used to mitigate the excessive responses of long‐span bridges. However, VDs face some intricate challenges in engineering practices, including high damping coefficient requirement, potential base shear amplification and tremendous damping force under high velocity. To address these issues, this study develops a
