We have developed a design method of output feedback controller suitable for a building -AMD system. This method can be generally applied to controlling multi modes of the system whose damping matrix does not necessarily satisfy the orthogonality condition. A reduced order model as well as reduced order weight matrix for optimal control are obtained through a linear transformation of the state space representation of the system considering the complex modes and output feedback gains are evaluated. This method is applied to controlling coupled transverse-torsional modes of a 4-story steel frame model with uniaxial eccentricity by two AMDs and the effectiveness of the method was verified both by numerical simulation and by shaking table test.
