[提要]  苏州工业园区国际大厦转换层就其双向大跨度、下部空间高度及上部负荷而言，尚不多见。设计提出了一种新型转换结构形式——“双向预应力转换梁体系”和支承细长柱临界荷载的计算方法。另外，对大楼的抗震概念设计、空间电算分析及试验分析作了介绍。

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.
