Abstract:The seismic isolation multi\|tower structure with enlarged base was analyzed using ideal particle system model to reveal relevant characteristics of seismic response of the structure. The design method of a practical project of the multi\|tower structure with enlarged base and seismic isolation base was discussed. It’s concluded that several analysis models should be taken into account to compare and design according to structural characteristics of different towers for the structure. And the stiffness of isolated story should be reduced as possible and an optimized yield force should be selected.
Keywords:multi\|tower structure; enlarged base; seismic isolation; complex structure
