Brief introduction of truss structure and space frame structure

As truss is reusable, non-polluting to the environment and made of non-polluting and environmentally friendly materials, it is more favored by enterprises. Truss is not only favored by enterprises in design scheme, but also it can be decorated with pictures and supplemented with lighting and supplementation to make the booth attract eyeballs to the maximum extent. This saves the exhibition cost and highlights the low featured price of the enterprise, which reduces a lot of waste.

Common forms of truss structure and space frame steel structure:

The common shapes of space frame are triangular cone, triangular prism, rectangular, truncated quadrilateral and so on. Usually bolted ball nodes, welded ball nodes, etc. This is a space structure.

Trusses are usually single row trusses, triangular trusses and quadrilateral trusses. The truss we often talk about is the quadrilateral truss, which is also the most widely used truss. Commonly used trusses are steel truss and aluminum alloy truss.

space joist can be supported on all sides and at multiple points, with large in-plane stiffness, and belongs to two-way force system.

Characteristics of truss and space frame:

Truss structure is developed on the basis of space frame structure. Compared with space frame structure, truss structure has its unique advantages and practicability, and the amount of steel used in the structure is more economical.

Trusses can also be designed in modular form, which is easy to be prefabricated and assembled, and is suitable for large-scale construction or transportation.

Space frame structure can withstand large spans and is widely used in structures such as roofs and bridges with large spans. It is able to provide stable support without using intermediate support and is suitable for buildings requiring large space, such as gymnasiums and airport terminals.

The lines of space frame structure are simple and smooth, which can form unique geometric forms with high visual aesthetics.

Both truss structure and space frame structure are light structure systems widely used in large-span buildings. Truss structure is composed of a series of rods and nodes, usually in triangular or other geometric forms, featuring high strength, light weight, economy and high material utilization rate, and is suitable for small and medium-span buildings such as bridges and roofs.

And the grid structure is a three-dimensional space frame structure, composed of a grid-like arrangement of rods and nodes, with strong spatial stiffness and stability, can withstand large spans and complex loads, widely used in stadiums, exhibition halls and other large space buildings. Both have become common structural forms in modern buildings due to their high material efficiency, easy construction and good seismic capacity, but the span and spatial adaptability of the mesh frame structure is stronger and suitable for larger scale projects.
