Monitoring of lateral stiffness changes for a real building using hysteresis loop analysis
Rabiepour, Mohammad; Zhou, Cong; Chase, Geoff; Rodgers, Geoffrey (2021-04-14)The BNZ building in Wellington, New Zealand was significantly damaged, and eventually demolished, due to the cumulative impact of three main earthquakes between 2013 and 2016. Although the building was equipped with a set ... -
Seismic behaviour of a non-linear structure with passive D3 viscous damper
Hazaveh, Nikoo; Rad, Ali; Chase, Geoff; Pampanin, Stefano (2021-04-14)Passive Direction Displacement Dependent (D3) viscous damper is a next generation of the conventional viscous damper could provide damping force in any desired quadrant to provide wanted damping hysteresis loop. This ... -
Upper and lower bound force capacity estimates of lead extrusion damper design force using classical extrusion models
Vishnupriya, Vishnupriya; Rodgers, Geoffrey; Chase, Geoff (2021-04-14)To reduce seismic vulnerability and the economic impact of seismic structural damage, it is important to protect structures using supplemental energy dissipation devices. High force to volume (HF2V) devices are supplemental ...
