Abstract Active control of structures against environmental loads, such as earthquakes and wind, has received much attention in the last decade. Much of this research has involved development of control algorithms based on the assumption of exact knowledge of the system parameters, a condition that does not always exist in real-life applications. In addition, most of this research effort has focused upon linear control. Few active control strategies can effectively handle control of nonlinear behavior. Fuzzy logic control provides a promising opportunity for this purpose. This paper discusses the motivations for using a Fuzzy Logic Controller (FLC) and the guidelines for its design. A brief description of a FLC is first outlined to introduce the appropriate definitions. The application of fuzzy control to nonlinear structures is then illustrated. Some numerical examples are presented to study the controlled response of a hysteretic plane frame under earthquake loading.
