Abstract: Recognizing the importance of limiting residual deformations that are usually associated with the response of full hysteretic systems under seismic loading, a number of energy dissipating devices and innovative structural ...

Abstract: Controlled rocking steel braced frames (CRSBFs) are intended to have a self-centering response that avoids damage to main structural elements. To ensure that all nonlinearity is confined to the intended elements at the ...

Abstract: Controlled rocking steel braced frames (CRSBFs) are being developed as a seismic force resisting system that can be constructed economically to avoid structural damage and residual deformations following an earthquake. In ...

Abstract: A new damping system, the viscoelastic coupling damper (VCD), has been developed to enhance the wind and seismic performance of coupled shear wall high-rise buildings by adding high damping elements in place of reinforced ...

Abstract: Base dual-mechanism systems that limit both shear force and overturning moment demands are being developed as a new class of seismic force–resisting systems to enhance the control of seismic demands at the base and along ...

Abstract: A new connection for steel moment-resisting frames that incorporates posttensioning elements to provide a self-centering capacity along with friction mechanisms to dissipate energy is proposed and experimentally validated. ...

Abstract: Replaceable links for eccentrically braced steel frames (EBFs) decouple the yielding links from the floor beams to facilitate rapid repair or replacement after a seismic event. Replaceable links that are composed of rolled ...
