Anti-seismic devices should be designed with proper safety margins against their failure, because the reliability of structural system where they are installed is strongly influenced by reliability. Seismic Standards generally prescribe factors (reliability factors) amplifying device responses at design condition, in order to reach a target level. In case Fluid Viscous Dampers (FVDs), these app...

Abstract This paper presents a practical multi-level performance-based optimisation method of nonlinear viscous dampers (NVDs) for seismic retrofit existing substandard steel frames. A Maxwell model is adopted to simulate the behaviour combined damper-supporting brace system, with fractional power-law force–velocity relationship NVDs, while distributed-plasticity fibre-based section approach us...

Performance-based optimization of energy dissipation devices in structures necessitates massive and repetitive dynamic analyses. In the endurance time method known as a rather fast analysis procedure, are subjected to intensifying excitations their response at multiple intensity levels is estimated by minimal number So, this significantly reduces computational endeavors. paper, employed determi...

Silicone fluids belong to the group of pseudoplastic non-Newtonian with complex rheological characteristics. They are considered in basic and applied researches a wide range industrial applications due their favorable physical thermal properties. One specific field automotive industry is working fluid viscous torsional vibration dampers. For numerical studies design development phase this dampi...
