Initial stiffness of self-centering systems and application to self-centering-beam moment-frames

Engineering Structures, 2020
Abstract There has been considerable development of self-centering seismic force resisting systems in the past few decades, many of which incorporate gap opening mechanisms. Experiments on these self-centering systems often result in an initial stiffness that is less than the predicted theoretical stiffness.

Self-Centering Frictional Damper (SCFD)

open access: yesEngineering Structures, 2019
Abstract 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 ...
