Abstract:The building height of No. 1 office building of Yaofeng Square in Kunming is 180-8m. It has irregular torsion, abrupt size change, discontinuous floor and partial irregularity (including cross-story column and inclined column). It belongs to a special irregular structure. The building adopts rectangular concrete filled steel tubular column + concentrically braced steel frame structural system, and buckling restrained braces are used in the bottom 14 stories, so it is a special type of high-rise building. The selection and layout of structural system, the design of two seismic defense lines, buckling restraint bracing design, design and strengthening measures for inclined column were introduced. In view of the out-of-code situation and weak parts of the project, appropriate performance objectives were proposed, and the calculation analysis and demonstration under frequent earthquake, fortification earthquake and rare earthquake were carried out by using software such as PKPM, ETABS and MIDAS/Gen, and corresponding strengthening measures were taken. The analysis results show that the structure can meet the requirements of relevant specifications and performance objectives.

Keywords:Yaofeng Square in Kunming; super high-rise building; concentrically braced steel frame; performance-based seismic design; inclined column; buckling restrained brace
