Self-Centering Frictional Damper (SCFD)
Engineering Structures, 2019Abstract This paper describes the behavior and design of a new self-centering frictional damper. This device is based on conic friction surfaces that lead to a flag-shaped hysteretic behavior. Its self-centering property and different possible configurations make it a very versatile device to be used in seismic applications of high-rise buildings ...

Seismic performance of self-centering glulam frame with friction damper
Engineering Structures, 2021Abstract The self-centering structure has good recentering capacity and seismic performance, and its application in timber structures can significantly reduce the residual displacement of the structure. In this paper, the seismic performance of the self-centering glulam (SCG) frame with friction damper (FD) is studied from three aspects: the test of ...

Development and parametric study of a new self-centering rotational friction damper
Engineering Structures, 2021Abstract Rotational friction (RF) dampers are among the efficient energy-absorbing devices with nearly elasto-plastic behavior and stable hysteresis response. However, the lack of self-centering features might result in undesirable residual displacement for the buildings equipped with RF dampers, not being re-occupiable quickly after severe events ...

Self-centering hybrid dampers for improving seismic resilience
Engineering Structures, 2021Abstract A comprehensive study on self-centering hybrid dampers (SCHDs) for improving seismic resilience is presented. The considered damper is composed of a pre-compressed friction spring part and a viscous fluid part. The pre-compressed friction spring part provides moderate strength, energy dissipating capacity and favorable recentering capacity ...

Experimental study on a self-centering RCS interior joint endowed with replaceable dampers
Journal of Constructional Steel Research, 2022Reinforced concrete column and steel beam (RCS) joints are typically designed to dissipate seismic energy by the inelastic deformation of plastic hinges developed at beam ends. This design results in difficult-to-repair damage and residual drifts. In this paper, as a result, a self-centering RCS interior joint with dampers that can be easily replaced ...

Self‐centering friction spring dampers for seismic resilience
Earthquake Engineering & Structural Dynamics, 2019SummaryThis paper presents a comprehensive study on self‐centering dampers equipped with friction springs. The basic mechanical behavior of individual friction springs is first understood via analytical descriptions that are verified by a preliminary experimental study.
