Abstract: A super high-rise building in First Plaza on Renmin Road in Kunming adopts steel frame-concentrically braced core wall structural system with the height of 160.5 meters. Selection of structural system and its layout were introduced. The overall calculation and analysis results could meet requirements of the current codes. Based on the targets of performance, the response spectrum and elastic time history analysis  under the frequent earthquake of the overall structure were carried out, as well as non-yielding analysis of key members under the moderate earthquake and the Pushover analysis of the overall structure. Measures were taken to strengthen the weak parts to ensure the high seismic performance under meeting the requirements of architectural features and reasonable economic conditions. Two methods for envelope design of the second seismic fortification line were introduced as well as the transformation of steel frames into steel reinforced concrete frames in the basement, which could provide references for structural design of similar projects.

Keywords: steel frame-concentrically braced core wall; performance-based seismic design; elastic time-history analysis; the second seismic fortification line; Pushover analysis
