Abstract: Reinforced concrete frame-core wall structure system is adopted for T1 tower, which is defined as B level super high-rise irregular building. The response spectrum analysis and elastic time history analysis under frequent earthquake together with elastic-plastic time history analysis under rare earthquake were carried out in order to satisfy the load capacity and ductility demands by different analysis softwares. Based on the analysis results, it is demonstrated that all the property index of T1 tower can meet the requirements according to specification, and this structure is safe and reliable with rational structural layout and good seismic performance.

Keywords: super high-rise building; frame-core wall structure; elastic-plastic time history analysis
