Abstract: A single-tower high-rise building with large base in Dongguan, which exceeds the height requirements of level B of the code, adopts the structural system of reinforced concrete frame-core wall with steel reinforced concrete columns at the bottom of peripheral frame columns.The structure system and the overall design indicators were briefly introduced, and the calculating results by different programs were analyzed. Performance-based design thought was evolved in the overall structure design and the component design.The main lateral force resistant components can meet the performance objectives of unyielding in the intermediate earthquake though some components still keep elastic.Dynamic elastic-plastic analysis under the rare earthquake was carried out and all the indicators can meet the requirements of performance-based seismic design.
Keywords: Out-of-code high-rise building; steel reinforced concrete column; performancebased seismic design; dynamic elastic-plastic analysis; buckling analysis
