The semi-active tuned liquid column damper (TLCD) system is investigated for control of coupled responses of 3D irregular buildings under seismic excitations. The TLCD system is a special type of tuned mass damper (TMD) system providing a performance similar to a TMD system but offers a number of practical advantages over the traditional TMD system. The equations of motion for the combined building and TLCD system are derived for multistory building structures with rigid floors and plan and elevation irregularities. Simulation results for control of two multistory moment-resisting space structures with vertical and plan irregularities show clearly that the semi-active TLCD control system reduces the responses of 3D irregular buildings subjected to earthquake ground motions efficiently.
