3. Performance-based Design Research Method
multimode-based energy dissipation design method is used to the performance-based design of eccentric frame-shell wall structure, which is combined with the principle of capacity spectrum method.

4. Performance-based Design
Performance target
Θ=0.125%

5. Performance-based Design

6. Performance-based Design
supplement damping ratio schematic diagram D1

7. Performance-based Design
the damping coefficien

8. Performance-based Design
Performance target
structure with dampers
structure without damper
interstory drift of structure with dampers obviously reduced，interstory drift become uniform and the performance of structure with dampers can reach the proposed target

9. seismic performance assessment
structure with dampers
