In this paper, the essential mechanics principle and the basic design procedure of triangular plate added damping on stiffness device （TADAS） were introduced. With typical design example, the application of TADAS on seismic design of high rised steel braced structure was introduced. The designed results were also analyzed. The results show that the appropriate installation of TADAS on structure system can improve the equivalent damping ratio and the seismic energy-dissipating capacity of whole structural system effectively, and also, it can decrease the seismic effect of structure system obviously. This paper can be referenced by the seismic design of similar projects.
