Structural system selection and out-of-code analysis of B block super high-rise building of Glory City in HaikouYao Qiyu, Zhang Chenjun, Liu Lijie, Gao Pengfei(Beijing Institute of Architectural Design, Beijing 100045, China)Abstract: B block super high-rise building of Glory City in Haikou is located in Meilan Distinct, Haikou City, Hainan Province, where the seismic precautionary intensity is 8 degree and the design basic acceleration of ground motion is 0.3g. The building which has the structural height of 149.4m adopts composite structure system of steel reinforce concrete frame and concrete core wall. The height of the building exceeds the Chinese code limit. According to the project characteristics, the structure system selection was discussed, the appropriate seismic performance objectives of the structure were set. Different programs were used to carry out response spectrum calculation and dynamic time-history analysis under the frequent earthquake, non-yielding design under the intermediate earthquake and Pushover analysis under the rare earthquake. Results show that structural indicators are reasonable and the overall structural design satisfies the expected requirements of the performance objectives.Keywords: Glory City in Haikou; super high-rise building; composite structure system; structure system selection; seismic performance objective
