Seismic 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...
متن کاملSeismic Response Reduction of Structures using Smart Base Isolation System
In this study, control performance of a smart base isolation system consisting of a friction pendulum system (FPS) and a magnetorheological (MR) damper has been investigated. A fuzzy logic controller (FLC) is used to modulate the MR damper so as to minimize structural acceleration while maintaining acceptable base displacement levels. To this end, a multi-objective optimization scheme is used t...
متن کاملEvaluation of the SEAOC/UBC97 Provisions for the Tall Base-Isolated Structures
The base isolation systems are among the passive control devices that have been used over the last three decades to limit the seismic-induced response of structures. In this regard, the Uniform Building Code provisions (UBC) has incorporated a special section for the seismic design of base isolated structures since its 1991 edition. Due to the importance of the behavior of these structures unde...

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...
