摘要:本文介绍了郑州升龙广场超高层写字楼的结构抗震设计，针对该结构，在分析与设计中采取了抗震性能设计方法和比现行规范更为严格的抗震措施；同时重点介绍了双向密肋空腔楼盖分析与设计的重点与难点；对本工程关键部位如型钢混凝土梁柱节点采取精细化空间设计方法，制定严格的施工控制措施，确保该结构达到预期的抗震性能设计目标和规范要求。

Abstract: The structural seismic design of the high-rise office building of Shenglong Square in Zhengzhou was introduced in this paper. According to the conditions, beyond code-specification, more strict anti-seismic measures than the current criterions and performance-based seismic design were adopted. Meanwhile, the emphasis and difficulty in the desigh and analysis of two-way hollow-ribbed floor are emphatically introduced.The space fine design and strict construction control measures were used to design the key components like section steel beam-column joints, which can ensure the structure to achieve the earthquake performance objectives and meet the requirements of the current code.
