Abstract :
    The main objective of reducing the structural response to the structural systems resisting lateral loads and structural life-is possible. Since earthquakes are random in nature passive structures that can be controlled with little ability to update its ability to reduce the frequency of different structures are earthquake. In recent years to address the problem of active and semi-active control system is used. Control system (whether active or semi-active) must have the ability to adapt to possible changes in load. The fuzzy control system due to the simplicity and robustness of a special place in the control is active. The purpose of this study was to evaluate the ability of the fuzzy controller with feedback system movement during an earthquake is to reduce the structural response. The results show the stability and capability of the control system in the presence of uncertainty in the earthquake, is in structural decline.
