Application of Truss Structure in Building Large Space Creation

As an efficient structural form, truss structure has a wide and important application in building large space creation.

Truss is a lattice structure made of rods connected by nodes. In the design of architectural large space, first of all, it has excellent bearing capacity. For large-span buildings such as exhibition halls, gymnasiums, terminals, etc., trusses are able to bear huge roof loads, self-weights and possible suspension loads (such as large sports facilities in gymnasiums, chandeliers in exhibition halls, etc.). Through reasonable arrangement and selection of rods, the loads are effectively transferred to the bearings to provide solid structural support for the large space and ensure the safety of the building under various working conditions.

From the perspective of space utilisation, truss structure has obvious advantages. Due to its own rod system, compared with solid beam structure, truss structure occupies relatively small space. This makes it possible to obtain a more open and transparent space effect inside the building, which will not cause a sense of oppression to people. For example, in gymnasium, the audience can have a view of the game without any obstruction; in exhibition hall, the exhibition area can be flexibly arranged without too much interference from structural members, so as to satisfy the functional requirements and spatial planning to the maximum extent.

In terms of modelling, truss structure shows great flexibility and diversity. It can be designed as plane truss, space truss and other forms, and by changing the length, angle and connection of rods, it can create rich and varied architectural shapes. Whether it is simple and smooth linear modelling or dynamic curved modelling, truss structure can be accurately realised. Like some landmark stadiums, the unique shape of truss structure not only meets the functional requirements of large space, but also becomes a very characteristic architectural landscape in the city, highlighting the artistic charm and personality of the building.

In terms of construction, truss structure mostly adopts prefabricated processing. In the factory, the rods can be produced and processed according to the precise design size, and then transported to the construction site for assembly. This way can effectively improve the construction efficiency, shorten the construction period, reduce the amount of wet work on site, and help to ensure the construction quality. Meanwhile, for some large truss structures, the methods of segmental lifting and overhead splicing can be adopted to reduce the construction difficulty and safety risk.

The application of truss structure in building large space construction realises the organic unity of structural performance, spatial effect, architectural shape and construction convenience, which provides strong technical support for the development of modern large space building, greatly promotes the innovation and progress of the construction field, and has an irreplaceable important position in many types of large public buildings.
