 As gateways to cities, airports and transportation hubs must simultaneously meet diverse demands for ultra-large span spaces, complex curved surface designs, and intelligent operational management. With their green, low-carbon, and modular technical characteristics, space frame structures have emerged as the ideal solution for such transportation facilities, demonstrating irreplaceable advantages in enhancing functionality and intelligence. 1. Functional Requirements and Technical Adaptation Modern airport and transportation hub designs confront three core challenges: (1) Creating column-free spaces spanning hundreds of meters to accommodate tens of thousands of passengers during peak hours; (2) Integrating complex electromechanical systems like baggage sorting and rail transit installations; (3) Ensuring long-term durability and operational safety. Space structures effortlessly span over 150 meters while weighing only one-third of concrete structures, significantly reducing found...

1. Structural Form Space Frame Structure A space frame structure is a space truss system formed by numerous members intersecting in space according to specific patterns to create multiple triangular or quadrilateral grids. These interconnected grids constitute a three-dimensional space structural system. It resembles a three-dimensional net-like structure where members crisscross in space to share loads collectively. For instance, common flat-plate space frames can be arranged in various configurations such as two-way orthogonal, two-way orthogonal skew, or three-way space frames. This structure evenly distributes loads across all members and nodes, offering superior spatial load-bearing performance.  Steel Trusses  Steel trusses are primarily planar structures. Straight members are connected at their ends through nodes to form triangular or other geometric units, which are then assembled into an integrated structure within a plane. Their shapes are relatively regular, typica...

The advantages of space   frame structure application The combination of reasonable form and high stiffness of the rods has strong seismic performance; the texture of the rods is lighter, which has the advantage of lightness under the premise of ensuring the stability of the space frame ; the space frame   rods and nodes are stereotyped; the arrangement of the components is flexible, etc. Bolt ball welded ball hybrid node analysis Bolt ball node and welded ball node both have unique application advantages, taking the hybrid node way that integrates two nodes can fully integrate multiple advantages and better meet the requirements of the project on the quality, adaptability and construction efficiency of the space frame   structure construction. When the space frame   structure adopts mixed nodes, the number of nodes of each type accounts for different ratios in general. Most of the ends of the rods are connected with bolted balls, and there are more bolted ball node...

      Long-span steel space frame structures are mostly used in multi-functional stadiums, conference and exhibition centers, expo halls, waiting halls, hangars, etc. The earliest flat space frame   with the largest span was the 91m×122m square quadrangular pyramid in the gymnasium of the University of California in Los Angeles in the 1960s. The largest double-layer reticulated shells are the Houston Astrodome (196m in diameter) and the New Orleans Superdome (207m in diameter) built in the United States in the 1970s. In the 1990s, a single-layer reticulated shell with the largest span in the world was built in Nagoya, Japan, with a building diameter of 229.6m and a structural diameter of 187.2m. Three-dimensional grids were used, and the nodes were rigid nodes capable of bearing axial force and bending moment. The largest indoor gymnasium in the world is the main gymnasium of the 1996 Olympic Games in the United States—the Atlanta Stadium (quasi-elliptical plane, 18...

  Space frame structure because of its novel structure, reasonable force, light weight, small amount of steel, a large number of steel structures have emerged from the late 1980s, increased by about 80 to 1 million m2 every year. Widely used in large sports venues, exhibition centers, theaters, shopping malls, terminal buildings, waiting halls, factory workshops, warehouses, TV towers, etc. The domestic space frame structure is mainly divided into: welding ball joint space frame and bolt ball joint space frame. The bolt ball joint space frame has a large amount of processing in the factory and convenient installation on site. It is suitable for the special-shaped structure with tight on-site construction period, restricted construction conditions and electricity consumption, complex grid shape and difficult pole positioning. This paper focuses on the bolted ball joint space frame. LF is professional manufacturer and engineering company for space frame and steel structur...
