Abstract:The main structure of B Tower of Chengdu Oriental Plaza was a super B high-rise building with height of 222-95m. Concrete frame-tube structural system was adopted in this building with larger tower and small tower connected at 32nd floor. The tower had a typical L-type plane. And it was a seriously irregular building with 5 general irregularities and 2 serious irregularities. Several analyses included overall elastic analysis, elastic time-history analysis and performance target check were carried out during the design process. Some key structural nodes were also calculated by FEA.And elasto-plastic time-history analysis under rare earthquakes was also performed by ABAQUS software to make the structure safe and feasible.
Keywords:super high-rise building; serious irregularity; connected structure; transform floor; elasto-plastic time-history analysis
