Aesthetic Expression Research of Steel Tubular Trusses

The aesthetic expression of steel tubular trusses stems from the unity of their mechanical logic and formal language. Through the repetition and variation of triangular stable units, they achieve both efficient structural force transmission and a rhythmic visual tension. For example, the Yellow River Bridge project combines spatial trusses and pipelines, meeting the functional requirements of a large span while the flexible design with a 15.7cm lateral displacement of the main cable endows the structure with a dynamic aesthetic.

Modern architecture places greater emphasis on the symbiotic relationship between steel tubular trusses and the environment. Cable trusses form light and curved surfaces through mast tensioning, such as the figure-eight cables in student work, which not only ensure lateral stability but also create a relaxed and expressive formal language. The use of color and light further enhances the structural expressiveness, transforming steel tubular trusses from engineering components into architectural symbols that combine function and art.
