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 کاملDynamic Response of Submerged Vertical Cylinder with Lumped Mass under Seismic Excitation
An analytical approach is presented to assess the response of offshore structures under seismic excitation. This paper evaluates the impacts of different fluid field models and the mass of equipment at the top of offshore structure which is simulated as lumped mass on the responses of offshore structures. To do this, two and three dimensional fluid field models are developed. In three dimension...
متن کاملFuzzy Control Strategy for Seismic Response Reduction of Smart Base Isolated Benchmark Building
Control strategy based on fuzzy algorithm is presented for response reduction of the seismically excited base-isolated building, which is an eight story base isolated non-linear building similar to existing buildings in Los Angeles, California. When a control method based on fuzzy algorithm to a structure is used for vibration reduction, it has inherent robustness, easiness to treat the uncerta...
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...
