[提要]  深圳地王大厦是一座高达368m，横向高宽比为8.78的超高层建筑，结构设计上遇到不少新的问题。该大厦结构系由日本新日铁株式会社设计部设计，作为该大厦的结构设计顾问，作者有机会与设计者就诸多重大设计技术问题进行了咨询与探讨。现就地王大厦风载的确定，结构抗风抗震设计，特别是怎样计算与控制结构在风和地震作用下顶点和层间位移等关键技术问题给予说明与探讨，最后简单介绍了大厦建成后进行监测和测试的初步结果。

The super-highrise structure of Di Wang Building is 368m in total height and the height-width ratio is 8.78 in transverse direction. A number of new and difficult problems were met and carefully dealed with in this building. As the structural consultant of the design firm-New Japan steel company, we had chance to study and discuss with the designers on a series of important technical problems that could not be covered in the present chinese design codes. This paper presents explanation and discussion upon some key technical problems such as wind load, earthquake and wind resistant design, displacement control under wind and earthquake action, etc. for structural design of the Di Wang building. Finally, some preliminary results measured on the constructed building are briefly introduced.
