The five high-rise office buildings are 119 meters high on the ground and the reinforced concrete cores are 125 meters high. They are out-of-codes high-rise buildings. The ultra-limit design instructions are proposed for these buildings. SATWE and ETABS were used to analyze the structure performance under vertical load, wind load and two different grades of earthquake and also checked the structure performance under high earthquake grade using SAP2000. The seismic performance of the corresponding target, take the seismic performance objectives for different parts of the structure, and analysis of the structural system of this project and measures for inspection by the above calculation. Analysis results show that the solutions are feasible, and the overall design meets code requirements.Keyword: out-of-codes high-rise buildings; seismic concept design; Pushover analysis
