日本的日本钢铁公司已经发展了一种新的、有效的、名为 N S 空间桁架体系的空间结构建造方法。据该公司所称,它简化了双曲室间结构的建造,并且能够简便地应用于大多数的空间结构形式及网型。空间结构体系是建造大空间钢结构所采用的方法之一。在近几年中,平板或单曲型的空间结构体系因为建造及装配简易,已经广泛应用。双曲型可提供更多的结构设计及较好的外观。在双曲型的情况下,需要起拱为平板室间 Japanese steel companies in Japan have developed a new and efficient method of building space structures called the N S space truss system. According to the company, it simplifies the construction of hyperbolic chambers and can be easily applied to most forms of space and mesh. Spatial structural system is one of the methods used to construct large space steel structure. In recent years, flat or single-type space structure systems have been widely used because of their ease of construction and assembly. Hyperbolic can provide more structural design and better appearance. In the case of hyperboloid, arching is required for the slab compartment
