Robust control of hysteretic base-isolated structures under seismic disturbances
The main objective of applying robust active control to base-isolated structures is to protect them in the event of an earthquake. Taking advantage of discontinuous control theory, a static discontinuous active control is developed using as a feedback only the measure of the velocity at the base. Moreover, due to that in many engineering applications, accelerometers are the only devices that pr...
متن کاملBehaviour of Base-Isolated Structures with High Initial Isolator Stiffness
Analytical seismic response of multi-story building supported on base isolation system is investigated under real earthquake motion. The superstructure is idealized as a shear type flexible building with lateral degree-of-freedom at each floor. The force-deformation behaviour of the isolation system is modelled by the bi-linear behaviour which can be effectively used to model all isolation syst...
متن کاملDisplacement–Based Seismic Design of Structures
The concept of designing structures to achieve a specified performance limit state defined by strain or drift limits was first introduced, in New Zealand, in 1993. Over the following years, and in particular the past five years, an intense coordinated research effort has been underway in Europe and the USA to develop the concept to the stage where it is a viable and logical alternative to curre...
متن کاملHierarchical semi-active control of base-isolated structures using a new inverse model of magnetorheological dampers
Magnetorheological (MR) dampers have received special attention as semi-active devices for mitigation of structural vibrations. Because of the inherent nonlinearity of these devices, it is difficult to obtain a reasonable mathematical inverse model. This paper is concerned with two related concepts. On one hand, it presents a new inverse model of MR dampers based on the normalized Bouc–Wen mode...
متن کاملSeismic Response Control Using Base Isolation Strategy
Earthquakes are one of the natural hazards that occur due to sudden violent movement of earth’s surface which releases energy and has destructive power in many parts of the world. The development of recent technologies for the control of seismic hazards catches the attention of structural engineers to make the structures seismically resistant. The seismic base isolation technique is a passive p...
