[摘要]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。

Abstract:Single-layer cable net curtain wall in high-rise buildings has been widely applied, and its structural system is composed of flexible steel cable. Because the stiffness of the cable net is obtained by applying pre-stress, it has more complicated mechanism than the traditional curtain wall structure, and its design and construction difficulties are high. Through three engineering examples, different single-layer cable net curtain wall structural forms were introduced. Detailed analysis was conducted on the key points and problems that need to pay attention to in the design and construction of single-layer cable net curtain wall structures. It provides references for reasonable selection of single-layer cable net curtain wall structure form for designers in the design of high-rise building structures, for accurately grasping the design elements in cable network structure, and for successfully structural design of the main structure and cable net curtain wall.
Keywords:single-layer cable net curtain wall; pre-stress; tension
