Multi-Span

The truss with a center column is a type of steel structure commonly used in the construction of prefabricated steel buildings. The characteristic of this truss frame is the presence of one or more intermediate support columns arranged along the length of the building, located between the main trusses, helping to reduce the distance between them.

Arranging the columns in the middle of the truss length helps to distribute the load more evenly, reducing stress on connection points and particularly lowering the risk of sagging in beams and roofs. As a result, the truss system with a center column can effectively meet the needs for long-span designs, especially in single-gable or multi-gable construction projects.

With a design featuring two or more rows of center columns, the maximum span can reach up to 200 meters, allowing for the expansion of usable space to the fullest. This flexibility enables the application of trusses with center columns in various large-scale projects such as warehouses, distribution centers, manufacturing plants, especially those requiring low roof slopes.

In addition to the advantage of wide spans, the center columns not only help optimize weight and reduce material costs but can also support the flexible division of internal areas within the structure. However, adding center columns may split the interior space, narrowing the continuous open area, which can limit visibility or movement flow. Therefore, the calculation of the location and distribution of the number of columns needs to be carefully considered to ensure a balance between economy, structure, functionality, as well as the arrangement of interiors, machinery, and functional zoning.
