Introduction to Steel Space Frame Structures

A steel space frame structure is a spatial truss structure composed of members and nodes connected according to certain rules. Its shape can be flat or curved. This structure features good spatial stress distribution, light weight, high rigidity, good seismic performance, and flexible architectural design. Steel space frames are widely used in the roof structures of large public buildings such as stadiums and industrial buildings. During construction, installation often employs a combination of ground assembly and overall hydraulic lifting and jacking techniques. Steel space frames are widely used in the roofs of large-span public and industrial buildings such as stadiums, theaters, exhibition halls, waiting halls, stadium grandstand canopies, aircraft hangars, and workshops with large column spacing. The construction and installation methods are mainly divided into two categories: one is the overall jacking, lifting, or hoisting method after overall ground assembly; the other is high-altitude installation, including high-altitude assembly, segmented assembly, and high-altitude sliding methods. Steel space frames offer flexible planar layouts and are suitable for various building plans such as rectangular, circular, elliptical, polygonal, and fan-shaped structures.

Introduction to Tubular Trusses

A tubular truss is a lattice structure composed of circular tubular members connected at the ends by welding or bolting. It is a type of spatial grid structure, primarily used in large-span public buildings such as stadiums, convention centers, high-speed rail platforms, and industrial plants.

This structure uses steel tubing as its main material. The cross-sections of the members are evenly distributed around the neutral axis, possessing strong resistance to compression, bending, and torsion. It can be designed in various forms, including simply supported trusses, arches, or frames. Compared to traditional space frame structures, it omits lower chord longitudinal members and spherical nodes, increasing material utilization by approximately 20%-30%. Compared to H-shaped steel trusses with open cross-sections, it eliminates the need for additional node plates, offering advantages in both structural simplicity and aesthetic appeal. The application of cold-formed thin-walled steel tubing further reduces self-weight, and precision machining of member welding nodes is achieved through intersecting line cutting technology.

A truss refers to a lattice structure composed of members connected at the ends; a tubular truss specifically refers to a structure where all members are circular tubular members. In most cases, the members of a truss are only subjected to axial tension or compression, and the stress is evenly distributed across the cross-section, thus maximizing the material's potential. These characteristics make truss structures economical in material usage and lightweight. They are easily shaped to suit various applications, such as simple trusses, arches, frames, and towers. Therefore, truss structures are widely used in many large-span stadiums, such as convention centers, sports stadiums, and other large public buildings.

Most members in truss structures are welded at the nodes. Before welding, the web members and chords must be pre-cut according to the weld shape of each member to be welded. This requires intersecting line cutting of the web member ends and slotting of the chord members. Because the members in a truss structure intersect with each other using intersecting lines, the cross-sectional shapes of the member ends are relatively complex. Therefore, in actual cutting and processing, both automated mechanical cutting and manual cutting methods are generally used.

Definition and Core Characteristics

Steel structure factory buildings are industrial buildings that use steel as the main load-bearing component. The main structure consists of steel columns, steel beams, steel roof trusses, etc., and is divided into light and heavy-duty types. Its core characteristics include:

1. Lightweight and High Strength: The strength of steel is far higher than that of concrete. For the same span, the weight of a steel roof truss is only 1/4 to 1/3 of that of a reinforced concrete roof truss, facilitating hoisting and providing superior seismic performance.

2. Short Construction Cycle: Most components are prefabricated in specialized factories, with on-site bolt connections. Dry construction is unaffected by seasons; a 300-square-meter factory building can be rapidly constructed in 3 days by 5 people.

3. Environmental Protection and Durability: The materials are 100% recyclable. With galvanizing and anti-corrosion coatings, the structural lifespan can reach decades or even a century, and it also has excellent thermal insulation properties.

4. Large span: Suitable for large-span structures, it fully utilizes the strength of steel, reduces the number of columns, and provides a spacious interior.
