［摘要］介绍了银泰时代中心超高层塔楼续建的结构设计情况。考虑已施工至4层的情况，对结构方案调整的思路及结构形式转变处关键部位设计进行了介绍，并对塔楼地上结构续建前后不同设计方案在地震及风荷载作用下的主要计算指标进行了比较；同时还对结构超限情况进行了大震弹塑性时程分析。根据比较及分析结果，提出相应抗震加强措施，并对已建成部分结构进行相应加固处理。结果表明，塔楼续建设计方案合理，能满足相关规范要求。

Abstract:The structural design of continued construction of Yintai Time Center super high-rise tower was introduced. Considering the situation that the tower has been constructed to four floors, the idea of structural plan adjustment and the design of key parts of the  structural form change were introduced, and the main calculation indexes of different design schemes before and after the continued construction of the tower’s ground structure under the action of earthquakes and wind loads were compared; At the same time, elastic-plastic time history analysis under large earthquakes for the structural out-of-code situation was carried out. According to the comparison and analysis results, the corresponding seismic strengthening measures were put forward, and the corresponding reinforcement treatment was carried out for some of the built structures. The results show that the design scheme for the continued construction of the tower is reasonable and can meet the requirements of relevant specifications.
