Seismic behaviour of a non-linear structure with passive D3 viscous damper
(New Zealand Society for Earthquake Engineering, 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 ...
Influence of damping models on nonlinear seismic response of a base isolated building
(New Zealand Society for Earthquake Engineering, 2021-04-14)
This paper discusses the effect of different damping models on nonlinear seismic response of a 8 storey 2D base isolated (BI) building: (1) Rayleigh damping proportional to the mass and initial stiffness matrices, (2) ...
Seismic response of a base-isolated building under pulse-like near-fault ground motions
(New Zealand Society for Earthquake Engineering, 2022-04-27)
Pulse-Like Near-fault ground motions are known to challenge base-isolated buildings with their capacity to create large isolation system displacements. Such earthquake records typically contain velocity pulses with long ...
