（蘇州工業(yè)園區(qū)設(shè)計研究院 215 021）[提要] 蘇州工業(yè)園區(qū)國際大廈轉(zhuǎn)換層就其雙向大跨度、下部空間高度及上部負(fù)荷而言，尚不多見。設(shè)計提出了一種新型轉(zhuǎn)換結(jié)構(gòu)形式——“雙向預(yù)應(yīng)力轉(zhuǎn)換梁體系”和支承細(xì)長柱臨界荷載的計算方法。另外，對大樓的抗震概念設(shè)計、空間電算分析及試驗分析作了介紹。
[關(guān)鍵詞] 雙向預(yù)應(yīng)力 轉(zhuǎn)換梁體系 支承細(xì)長柱 轉(zhuǎn)換層The transfer floor of Suzhou Industrial Park International Building is unusual as far as its two-way large span' the height of the space below and the load above are concerned. This paper presents the design of a new transfer structural system-two-way prestressed transfer girder system, and the calculation of the critical load of the slender support columns. In addition, the conceptual design of earthquake resistance, the space analysis with software and the test analysis of the building are introduced.
Keywords: two-way prestress; transfer girder system; slender support column; transfer floor
