高大立面幕墙骨架结构设计研究

Research on the skeleton structure design of tall facade curtain wall

现代建筑中高大的立面幕墙应用广泛,大多应用在机场航站楼、铁路车站、会展建筑、高端酒店等大型公共建筑。结合国内外机场航站楼等项目中的优秀幕墙设计案例和工程实践,按构件类型和传力路径对幕墙骨架结构进行分类评价,梳理设计幕墙支承结构体系的思考过程。由于高大幕墙的骨架结构直接外露,综合考虑结构特点、幕墙尺度、支承条件、建筑外观等因素,选择适用的、高效的骨架结构体系和构件形式,以及连接节点的精细化、一体化设计是影响幕墙设计方案优劣。

Tall facade curtain walls in modern buildings are widely used, especially in large public buildings such as airport terminals, railway stations, exhibition buildings and high-end hotels. Combined with excellent curtain wall design cases and engineering practices in domestic and foreign airport terminals and other projects, the skeleton structure of curtain wall was classified and evaluated according to the component type and force transmission path, and the thinking process of designing the curtain wall supporting structure system was sorted out. Since the skeleton structure of the tall curtain wall is directly exposed, comprehensively considering the structural characteristics, curtain wall scale, supporting conditions, building appearance and other factors, selecting the appropriate and efficient skeleton structure system and component form, and considering the refined and integrated design of the connection joints can influence the pros and cons of curtain wall design.
