Abstract: Modern civil engineering structures are long and slender and they have less damping. Therefore they are subjected to large vibrations when earthquake or wind acts. These excitations may cause structural collapse of the structure. Therefore to control these vibrations supplementary control devices are used. Tuned liquid column damper (TLCD) is one of a passive control device to reduce the excitations. TLCD will transfer the energy from the structure to TLCD by the motion of water in a U-shape tube like devices fitted with an orifice opening. Due to this motion the excitations will reduced. Also a fuzzy controller is designed to control the output of the TLCD. In this paper, particle swarm optimized (PSO) fuzzy controller was introduced in to the TLCD-structure system. The PSO will optimize the IF-THEN rules of fuzzy controller. The optimized results are compared with structure without TLCD, and fuzzy controlled TLCD-structure system. From this paper, the vibrations can be effectively suppressed with the proposed fuzzy controller. Research India Publications.
