Abstract:The height of Kaidi Center out-of-code high-rise building in Wenzhou is 278m. The cast-in-situ reinforcedconcrete frame-core tube structure was adopted after analysis and comparison. The building belonged to the out-of-codehigh-rise structure due to a series of out-of-code items such as out-of-code height,stiffness mutation,discontinuous floor,torsion irregularity,cross-layer column and inclined column. The performance-based design was carried out according toseismic performance target C. Calculation and analysis were applied integrally and locally to the structure by YJK andMIDAS,including frequent earthquake seismic analysis and elastic time-history analysis,medium earthquake seismicanalysis,equivalent elastic analysis of rare earthquake,etc. The elastic-plastic time-history analysis of rare earthquake wascarried out by PKPM-SAUSAGE. The result of calculation show that the structure can meets the requirements of thecorresponding code and the design agrees with the preset performance objectives of seismic design,which indicates that thestructural system is feasible and the selection of structural members is reasonable.
