Nonlinear Spectral Analysis for Structures with Re-centring D3 Viscous Dissipaters
This research investigates hybrid dissipation combining self-centring ring-springs with direction- and displacement-dependent viscous devices to enable low-damage, re-centring structural connections. Hybrid devices adding 10–35% equivalent viscous damping and 20–40% of structural stiffness are evaluated using response spectra over a suite of design level events. Average reductions in peak and residual drifts up to 55% and 73%, respectively, are obtained for hybrid device-enabled structures at a cost of 89% increases in base shear over the baseline structure. The overall results illustrate the trade-off of dissipation and re-centring goals when hybrid devices are used.
