单层索网幕墙在高层建筑中应用已经非常广泛,其结构体系由柔性钢索组成。由于索网的刚度需通过施加预应力获得,其与传统幕墙结构相比具有受力复杂、设计和施工难度较高等特点。通过三个工程实例,介绍了不同的单层索网幕墙结构形式,详细分析了单层索网幕墙结构在设计和施工中要把握的要点以及需要注意的问题,为设计人员在高层建筑结构设计中合理地选用单层索网幕墙结构形式、准确把握索网结构的设计要素、顺利完成主体结构和索网幕墙结构的设计提供参考。
Single-layer cable network in the high-rise building has been widely used, the structural system consists of flexible steel cable. As the stiffness of the cable network is obtained through the application of prestress, it has the characteristics of complex force, high design and construction difficulty as compared with the traditional curtain wall structure. Through three engineering examples, the different forms of single-layer cable-net curtain wall are introduced. The key points to be grasped in the design and construction of single-layer cable-net curtain wall structure and the problems to be noticed are analyzed in detail. In the reasonable selection of single-layer cable network structure of the curtain wall, accurate grasp of cable network design elements, the successful completion of the main structure and cable network design of the curtain wall provides a reference.
