This paper presents a simplified design procedure (SDP) for performance-based of low-rise new steel MRF buildings with nonlinear viscous dampers. The SDP uses an effective stiffness and equivalent damping multi degree-of-freedom (MDOF) model the building, which is established using linearized system (damping devices associated bracing). integrated process to achieve target performance objective...

In addition to elastomeric devices, viscous fluid dampers can reduce the vibration transmitted dynamic systems. Usually, these are rate-independent and used in conjunction with isolators insulate base of buildings (buildings, bridges, etc.) shocks caused by earthquakes increasing damping capability. According EN 15129 standard, velocity-dependent anti-seismic devices Fluid Viscous Dampers (FVDs...

This paper discusses the damping measurements on cables with real-time controlled MR dampers that were performed on a laboratory scale single strand cable and on cables of the Sutong Bridge, China. The control approach aims at producing amplitude and frequency independent cable damping which is confirmed by the tests. The experimentally obtained cable damping in comparison to the theoretical va...

This work aimed to improve the vehicle body stability and ride comfort of tracked military crew. For this purpose, magnetorheological fluid dampers were used. process has made theoretical model platform a semi-active suspension system. modification allows for application different control laws these systems. The usage continuous skyhook law assumes influence three fictitious viscous dampers. Th...

Viaducts with roller bearings are subject to large displacement, which could lead the collapse of deck during earthquakes. This study attempts prevent displacements by installing steel stoppers at both sides bearings. The efficiency viscous damper stiffness on seismic performance curved viaducts combined use a spatial multipoint is evaluated. pounding phenomena exactly simulated, considering en...
