The device acts as two independent and orthogonal tuned liquid column dampers (TLCDs), but due to its configuration it requires less liquid than two equivalent independent TLCDs. The equations of motion of the system formed by the BTLCD and the primary structure to be controlled, are obtained by means of Lagrangian dynamics explicity considering the non symetrical action of the damping forces. First, the primary structure was assumed to have two degrees of freedom (DOFs). Assuming that the system is excited by a base acceleration that can be considered to be a white noise random process, the optimum design parameters of the device were obtained to minimize the response of the primary structure. The optimum design parameters are presented as expressions covering a wide range of possible configurations for the device in a controlled structure. The use of a BTLCD to control the seismic response of several DOF structures was also studied, showing that if the structural response occurs mainly in two perpendicular modes, then the optimum design parameters for two DOF structures can be used. Finally, experimental analysis of the BTLCD for controlling the seismic response of 3-story structure scale model are developed in order to verify the effectiveness and accuracy of the equations and design procedures proposed herein.
