Renewable Resources Exchange Project with 185.80m tall and 41 floors adopts concrete filled rectangular steel frame-core wall structure system. The structure system was analyzed after out-of-code cases were introduced. Reasonable seismic performance objectives were developed, and overall structure analysis was carried out using two different softwares under frequent earthquake, moderate earthquake and rare earthquake cases respectively. Weak floors and parts were discovered in elastic-plastic time-history analysis, and strengthened in construction drawing design phrase to achieve the seismic precautionary objectives. Results show that structural design for complex high-rise structure should be based on performance-based seismic design method using elastic and elastic-plastic analysis, in order to achieve desired performance objectives. Calculation under moderate earthquake and rare earthquake cases should be adjusted according to the out-of-code amendments of experts, so as to direct the construction drawing design.Keywords: super tall building; performance objective; seismic calculation; elastic time-history analysis; static elastic-plastic time-history analysis作者简介:邱焕龙,学士,一级注册结构工程师,Email:job575@126.com。参考文献[1]JGJ 3—2010高层建筑混凝土结构技术规程[S].北京:中国建筑工业出版社,2011.[2]GB 50011—2010建筑抗震设计规范[S].北京:中国建筑工业出版社,2010.[3]JGJ 99—98高层民用建筑钢结构技术规程[S].北京:中国建筑工业出版社,1998.[4]窦南华,吴一红.中国供销集团再生资源交易所项目初步设计抗震设防专项审查意见[R]. 2012.
