This study deals with the design of a bi-directional liquid damper for SDOF structure. Two dampers are usually needed to reduce wind-induced responses tall structures since they along and across wind ones. The proposed has advantage controlling both single damper. shows dynamic behavior tuned column (TLCD) sloshing (TSD) in direction two axes perpendicular each other. paper presents experimental verification confirm its control performance. First, shaking table test is carried out investigate reducing structure by Control performance expressed transfer function from accelerations Testing results show that reduced Also, it torsion responses. It was confirmed system identification damping ratio increased
