Abstract

Different techniques are used to decrease structural responses under earthquakes. Base isolation system is a passive technique which reduces relative displacement and acceleration of the structure, simultaneously. However, it sometimes increases the absolute displacement. Using active control force in the isolated system is an effective method to overcome this problem. In this paper, the erformance of an 8-story steel framed benchmark structure with base isolation is improved using a combination of multi-tuned mass damper (MTMD) and an active control force at the isolation level. The effects of proposed method in minimizing the response of the structure under four near-field ground motions are investigated. The control force is determined using the Fuzzy Type-1 algorithm. The MTMD consists of two TMDs, which are placed on the first floor and on the roof. In addition, the effects of pulse-like shape in near-field earthquakes on response of controlled structure are examined. Based on the results obtained from the time history response, it is revealed that MTMD reduces relative displacement andabsolute acceleration in two directions (x, y) up to a maximum value of 66% and 47%, respectively. The hybrid base isolation controller reduces absolute displacement by a maximum of 33%. Based on the results, it is possible to reduce the twisting in the irregular structure by the placement of actuators in the four corners of the architectural plan
