Estimation of Cyclic Demand in Metallic Yielding Dampers Installed on Frame Structures
Applied Sciences, 2020 The efficacy of hysteretic dampers can be formulated as the number or equivalent inelastic cycles, or the ratio of normalised dissipated energy to displacement ductility. This parameter is used in the design of framed structures with supplemental dampers

Evaluation of effects of hysteretic damping of shape memory alloys on seismic performance of tuned mass damper [PDF]
Journal of Structural and Construction Engineering, 2019 Tuned mass damper is a common tool in passive control, which is used in many structures. However, with all the proper features, its most important functional limitation is the weakness against broad band excitation.

The Effects of Dynamic Loading on Hysteretic Behavior of Frictional Dampers [PDF]
Shock and Vibration, 2014 During an earthquake excitation, a frictional damper may experience many cycles of dynamic loading. The effects of wear and heat induced by the cyclic loading result in the possible decay of the slippage load which subsequently reduce the energy absorption of the damper.
