摘要: 为保证 2019 年北京世园会艺术中心项目屋面板足够轻薄,创新地将屋面板设计成双层钢板的空腹结构板,形成钢板组合薄壳结构.基于此项目,分别从结构设计、构造措施、连接节点以及施工工艺等方面对该项目采用的钢板组合薄壳结构进行了详细介绍.同时介绍了钢板组合薄壳结构在 2022 年北京冬奥会崇礼冬奥村下沉庭院的景观连廊中的应用.通过钢板组合薄壳结构在上述两个项目中的成功运用,钢板组合薄壳结构不仅对自由曲面上人屋盖适应性较好,同时在人行连廊上同样能够表现出良好的受力性能,适用于建筑师对结构的几何尺寸要求较高的平面、曲面建筑,尤其适用于重载楼屋盖和大跨度楼屋盖.

Abstract: In order to ensure that the roof panel of the 2019 Beijing World Horticultural Exhibition Art Center project islight enough,the roof panel was innovatively designed as a double-layer steel plate hollow structure plate,forming a steelplate combined thin shell structure. Based on this project,the steel plate combined thin shell structure adopted in thisproject was introduced in detail from the aspects of structural design,structural measure,connection node and constructiontechnology. At the same time,the application of the steel plate combined thin shell structure in the landscape corridor ofthe sunken courtyard of the Chongli Winter Olympic Village in the 2022 Beijing Winter Olympics was introduced. Throughthe successful application of steel plate combined thin shell structure in the above two projects,the stecl plate combinedthin shell structure not only has good adaptability to the master′s roof on the free-form surface,but also can show goodmechanical performance on the pedestrian corridor. The steel plate combined thin shell structure is suitable for flat andcurved buildings where architects have high requirements on the geometric dimensions of the structure,especially for heavy-duty building roofs and large-span building roofs.
