A Semi‐active piezoelectric friction damper
Earthquake Engineering & Structural Dynamics, 2014 SummaryThis research investigates the development of a semi‐active piezoelectric friction damper for controlling the seismic response of large‐scale structures. The proposed device is made of Duplex steel and leads to high friction capacity, which can be developed either in passive or semi‐active modes.

Modelling and design of a dual channel magnetorheological damper [PDF]
, 2013 © Cranfield UniversityA limitation with the current analytical models for predicting the performance of a magnetorheological (MR) damper is that they fail to capture the hysteretic variation of force versus velocity variation correctly.

Semi-Active Control of Post-tensioned Steel Frames [PDF]
, 2013 After the Northridge 1994 earthquake it was found that failures in steel frame buildings were mainly concentrated in beam-column connections. This prompted researchers to work on improvements, mainly focussed on increasing the rotational ductility ...

Enhancing Friction Pendulum Isolation Systems Using Passive and Semi-Active Dampers
Applied Sciences, 2020 Friction pendulum systems (FPSs) are a common solution for isolating civil engineering structures under ground movements. The result is a base-isolated structure in which the base exhibits low shear stiffness in such a way that the input energy of the ...

Experimental Evaluation of Modified Groundhook Car Suspension with Fast Magnetorheological Damper
Actuators, 2022 The car suspension setting is always a trade-off between comfort and handling. The semi-active damper system seems to be an option for reducing the compromise between the two demands.
