Energy dissipation technology was applied in seismic design and tests of dampers performance were conducted. Features of structure design, such as structure form selection, damper selection and layout were introduced. Performance of structure was studied under frequent and rare earthquakes, through finite element software called ABAQUS. The results of the elasto-plastic time-history analysis under three different earthquakes were compared and it is found that treatment measure and the energy dissipation design to the limited-beyond high-rise building improved the structure's seismic performance.Keywords: High-rise structure; frame-shear wall; Seismic analysis; nonlinear time-history analysis;
