Abstract

SEMI-ACTIVE CONTROL devices, also called “Intelligent” control devices, constitute the positive aspects of both passive and active control devices. A SEMI-ACTIVE CONTROL strategy is similar to the active control strategy, but this control device has been shown to be more energy-efficient than active devices. A particular type of SEMI-ACTIVE CONTROL device, the Variable Stiffness Device (VSD), consists of a hydraulic cylinder with a normally closed solenoid control valve inserted in the tube connecting the two cylinder chambers. This paper emphasizes on the application of Semi-active Fuzzy Logic Controller (SFLC) of this system for getting the best results in the reduction of the building responses under earthquake excitations.For the numerical example, a 12-story building, located in the city of Rasht, Iran, is modeled as 3-D frame and the problem is solved in state space. The results obtained from the proposed control scheme (SFLC) are compared with those obtained from the ON-OFF control method. It is found that the SFLC is highly effective in reducing the responses of the example building than the ON-OFF ALGORITHM. In this study, the optimal values of the fuzzy rule bases, membership functions, and the location of the control device are determined.
