( Dalian Institute of Urban and Architecture Design, Dalian 116021, China)Abstract: The height of the A tower of Dalian Jiahe Plaza reaches 184.5 m.The design of the foundation and the features of the structure system were introduced. The performance-based design method of the concrete-filled steel tube frame-concrete core-wall structure was analyzed. The seisnuc performance objective is set to C level. On the 25ffi and 38'h floor, two outriggers are set up in order to reduce the displacement of structure and to strengthen the lateral stiffness. In the stiffened story, the composite steel reinforced concrete columns is set up in order to heighten ductility of the structure, analyses the structural anti-seismic performance in rare earthquake through the static elastic-plastic method.
Keywords: super lugh-rises building; CFT column; performance-based design method; static elastic plastic analysis
