Abstract:Super high-rise tower building of Huancheng HNA Center is a complex high-rise building exceeding B-level requirement of height in the code. There are irregularities including irregular torsion and partial discontinuity of floor. The performance-based seismic design method was adopted in the design. Different performance targets were adopted according to the importance of the components. The elastic analysis under frequent earthquakes, the elastic time-history analysis under frequent earthquakes, the performance design under fortification earthquakes, the elastic-plastic time-history analysis under rare earthquakes and simulated seismic shaking table test were performed. The results of calculation and analysis show that the seismic performance of the whole structure and its components can reach the expected targets, and the theoretical calculation is basically consistent with the model test results.
Keywords:Huancheng HNA Center； super high-rise building; elastic-plastic time-history analysis; seismic performance; shaking table test
