（中國建筑科學(xué)研究院深圳分院 深圳 518028）[提要] 深圳地王大廈是一座高達368m，橫向高寬比為8.78的超高層建筑，結(jié)構(gòu)設(shè)計上遇到不少新的問題。該大廈結(jié)構(gòu)系由日本新日鐵株式會社設(shè)計部設(shè)計，作為該大廈的結(jié)構(gòu)設(shè)計顧問，作者有機會與設(shè)計者就諸多重大設(shè)計技術(shù)問題進行了咨詢與探討?，F(xiàn)就地王大廈風(fēng)載的確定，結(jié)構(gòu)抗風(fēng)抗震設(shè)計，特別是怎樣計算與控制結(jié)構(gòu)在風(fēng)和地震作用下頂點和層間位移等關(guān)鍵技術(shù)問題給予說明與探討，最后簡單介紹了大廈建成后進行監(jiān)測和測試的初步結(jié)果。
[關(guān)鍵詞] 超高層建筑 框筒結(jié)構(gòu) 風(fēng)荷載 抗震設(shè)計 位移控制 鋼-混組合結(jié)構(gòu)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.
Keywords: super-highrise structure; frame-tube structure; wind load; seismic design; displacement control; steel-concrete composite structure
