Abstract:Based on a super highrise building shear wall structure with large aspect ratio, analyses on the seismic performance were carried out including elastic CQC method analysis, elastic timehistory analysis under the frequent earthquake, elastic and nonyielding calculation analysis under the precautionary earthquake and dynamic elasticplastic timehistory analysis under the rare earthquake. The mechanical characteristics key problems of the structure under each level earthquake were analyzed, and corresponding
strengthen measures were adopted. Results show that with corresponding calculation methods, and strengthening measures, the super highrise shear wall structure with large aspect ratio can meet the seismic performance objectives.
Keywords:large aspect ratio; shear wall structure; super highrise building; seismic performance analysis
