چکیده

During the last two decades, active and semi-active control of civil engineering structures has made rapid progress in Japan. This technology has become widely used in earthquake engineering design, and more than 50 control systems have already been applied to buildings in Japan. The 1995 Hyogo-ken Nanbu Earthquake opened a door to positive development of semi-actively-controlled buildings against large earthquakes. This paper reports the state of the art by introducing practical applications, and describes future perspectives.

Multi-objective Optimization of Semi-active Control of Seismically Exited Buildings Using Variable Damper and Genetic Algorithms

Semi-active fluid viscous dampers as a subset of control systems have shown their ability to reduce seismic responses of tall buildings. In this paper, multi-objective optimization of the performance of this group of dampers in reducing the seismic responses of buildings is studied using multi-objective genetic algorithms. For numerical example, two 7 and 18 stories buildings are chosen and mod...

An optimal semi-active thermal exchange-Fuzzy logic Controller for Structural Dynamic Control and Rehabilation

The effect of intelligent semi-active thermal exchange-fuzzy controller in structural rehabilitation by attenuating seismic responses of structural systems is investigated. In the suggested control system, MR dampers and sensors are employed as a semi-active controller. Resultant control forces of MR damper are administrated by providing external voltage supply, during the earthquakes and high ...
