各种大跨度建筑结构体系类型(国外英文资料) This paper discusses the types of large span architectural structures In large span structures, the more diffuse the branch points of the structure, the stronger the constraint on the layout of the plane and the spatial combination. Conversely, the more concentrated the supporting points of the structure, the greater the flexibility. Based on the analysis of the structure of various large span Spaces, this paper discusses the structure type system, which can be used to enlighten the peers. [keywords] large span space structure; Arch structure; The dome structure; 椼 frame structure; Space truss structure; Shell structure; Cable structure; Membrane structure The structure of vault and vault In order to maintain stability, the structure must have a firm and wide support. To form the space by a cylindrical arch, it is reflected that there must be two thick and thick side walls which are parallel to each other, and the larger the arch, the thicker the wall that supports it. Obviously, this inevitably affects the flexibility of the spatial composition. In order to overcome these limitations, people in the long-term practice and on the basis of one-way trunk arch, create a two-way crossover cylindrical arch, in order to building the development of the popular and create the dome structure. Dome structure is an ancient form of large span structure, in large span structure, the structure of the fulcrum is scattered, the plane layout and space combination of the stronger the binding; Conversely, the more concentrated the supporting points of the structure, the greater the flexibility. From the earliest cylindrical arches to high straight pointed arch ribs; From the semi-spherical structure of the dome to the structure of the vaulted dome, it shows that the relative concentration of the supporting points gives great flexibility to the spatial combination. The structure of the stations and the structure of the lattice The frame is also a large span struct
