A bi-axial tuned liquid mass damper(TLMD) was proposed and evaluated on its control performance. The proposed TLMD controls structural response in a specific one direction by using the liquid sloshing of TLCD. Also, the TLMD controls structural response in the other orthogonal direction by TMD behavior which mass consists of the container itself and liquid within container of TLCD installed on linear motion guides. Force-vibration tests on a real-sized structure with the TLMD were performed to verify its independent behavior in two orthogonal directions. Test results showed that the responses of a structure were considerably reduced by using the proposed TLMD and its usefulness for structural control in two orthogonal directions.
