Active tuned mass damper (ATMD) control systems for civil engineering sb.uctures have attracted considerable attention in recent years. This paper emphasizes on the application of fuzzy logic (FLC) to design control scheme for getting the best results in the reduction of the building response underearthquake excitations. Therefore, the proposed method has the advantages of the fuzzy logic controller (FLC) to handle the uncertain and non-linear phenomena. The building is modeled as a shear frame and the problem is solved in state space. The proposed method is applied to an 11-stosy realistic building.The results obtained from the proposed control scheme (FLC) are compared with those obtained from the TMD, and linear quadratic regulator (LQR) control methods. It is found that the FLC is highly effective in reduction of the seismically excited benchmark building
