Abstract:Tower 8 of Shantou China Resources Center  is a high-rise building with six-story commercial podium at the bottom and business office at upper part. There are irregular items in the project including torsional irregularity, dimension mutation, discontinuity of vertical component and high level transfer with columns. The performance-based seismic design method was used with a C-level performance target. According to Guangdong technical specification for concrete structures of tall building, the structure was analyzed under frequent earthquake and wind load. The key structural components were checked through equivalent elastic method under fortification and rare earthquakes. The elastic-plastic dynamic time-history analysis using PKPM-SAUSAGE program was taken to research the overall structural performance and the plasticity development of key components under the rare earthquake. The results show that all the key structural components meet the established seismic performance objectives and the structure has a good seismic performance.

Keywords:high level transfer; discontinuity of vertical component; torsional irregularity; performance-based seismic design
