000011276 520__ $$2eng$$aDesign method based on the elastic stiffness for friction energy dissipation braced frame structure was studied in this paper. Firstly, original multi-degree-of-freedom (MDOF) system without braces was transformed into an equivalent single-degree-of-freedom (E-SDOF) system by means of an assumed vibration mode, and the relationship between elastic stiffness of SDOF system and its seismic action was deduced according to the design spectrum. Then the equivalent seismic action of global structure with braces was calculated by drift limit, stiffness and mass layout of original structure, and the seismic action distribution of global structure was estimated according to the seismic distribution of the original system. The numerical example demonstrated the procedure of this design method. Finally, precision improving method by means of interim drift limit was proposed.
