Journal ArticleDOI
Performance of a damage‐protected beam–column subassembly utilizing external HF2V energy dissipation devices
Geoffrey W. Rodgers,K.M. Solberg,J. Geoffrey Chase,John B. Mander,Brendon Bradley,Rajesh Dhakal,Luoman Li +6 more
TL;DR: In this article, the authors present an experimental investigation employing an alternative to mild steel: a high force-to-volume (HF2V) class of damper-based energy dissipation devices.
Journal ArticleDOI
Damage Avoidance Design Steel Beam-Column Moment Connection Using High-Force-to-Volume Dissipators
Thomas J. Mander,Geoffrey W. Rodgers,J. Geoffrey Chase,John B. Mander,Gregory A. MacRae,Rajesh Dhakal +5 more
TL;DR: In this article, the beam-column joint region consists of a top flange-hung beam connected to the column by an angle bracket, and high-force-to-volume (HF2V) devices are attached from the column to the beam to provide joint rigidity and energy dissipation as the joint opens and closes.
Journal ArticleDOI
Re-shaping hysteretic behaviour using semi-active resettable device dampers
J. Geoffrey Chase,K.J. Mulligan,Alexandre Gue,Thierry Alnot,Geoffrey W. Rodgers,John B. Mander,Rodney B. Elliott,Bruce Deam,Lance Cleeve,Douglas Heaton +9 more
TL;DR: In this article, a one fifth scale semi-active, resettable device is designed and tested to determine the efficacy of this controllable form of supplemental damping, which is essentially non-linear spring elements that are able to reset their rest length actively, releasing stored energy before it is returned to the structure.
Journal ArticleDOI
High-Force-to-Volume Seismic Dissipators Embedded in a Jointed Precast Concrete Frame
Geoffrey W. Rodgers,K.M. Solberg,John B. Mander,J. Geoffrey Chase,Brendon Bradley,Rajesh Dhakal +5 more
TL;DR: In this paper, an experimental and computational study of an 80 percent scale precast concrete 3D beam-column joint subassembly designed with high force-to-volume dampers and damage-protected rocking connections is presented.
Journal ArticleDOI
Experimental Studies on Cyclic Performance of Column Base Strong Axis–Aligned Asymmetric Friction Connections
TL;DR: In this paper, an asymmetric friction connection (AFC) at the base of a steel column such as may be used in a moment-frame is described. But, it is not shown that the connection can tolerate high levels of drift without significant strength degradation.
