Abstract: The AUX project in Future Sci-Tech City of Hangzhou is a large-scale building integrating commerce, officeand hotel, which consists of a super high-rise tower building with 59 floors and a commercial podium building with 6floors. The structural system of the tower building is composed of concrete-filled rectangular steel tubular columns,steel frame beams, reinforced concrete corewall and three ring belt waist trusses arranged on mechanical floors andrefuge floors. Due to the limitation of architecture functions and objective conditions, there are structural irregularitiessuch as out-of-code height, eccentrically arrangement, large opening in the floor, abrupt change in shear bearingcapacity, inclined columns, through-story columns, etc. , and the structure belongs to the out-of-code high-risestructure with irregular shapes. Aiming at the irregularity of the structure, the performance-based seismic design wasadopted to perform elastic analysis under the action of frequent earthquakes, structural check calculations under theaction of fortification earthquakes, and elasto-plastic analysis under the action of rare earthquakes. And correspondingseismic strengthening measures were proposed for weak parts of the structure. So that the structure could meet therequirements of the expected C-level seismic performance design target in general. In addition, construction simulationand analysis of the impact of shrinkage and creep were carried out on the structure, providing reference and basis forsubsequent design and construction.

Keywords:super high-rise building; ring belt waist truss; seismic strengthening measure; performance-based seismicdesign; construction simulation; shrinkage and creep
