Abstract
A column-shear-wall transfer structure with the mixed lead viscoelastic dampers was designed. The response spectrum analysis and local nonlinear time history analysis in frequently occurred earthquake and seldomly occurred earthquake of the column-shear-wall transfer structure
added with the mixed lead viscoelastic dampers and steel braces of the frame story
are completed.The results show that the interstory displacement of the structure with energy dissipation devices can meet the seismic performance demands of Code for Seismic Design of Buildings in frequently and seldom occurred earthquakes
and the inter -story displacement and torsional deflection are smaller than the structure with steel braces.Compared with the structure with steel braces
the behavior of the structures upper the transfer story is not influenced. Therefore
the seismic behavior of column-shear-wall structure with energy dissipation devices had been obviously improved due to the energy dissipation devices
and turned into multi-defence systems of seismic engineering.
