Engineering Application Examples of High-Strength Steel Structures

With the development of high-strength steel, Western developed countries have fully recognized the application advantages of high-strength steel and have begun to increase its use in various fields. Overall, most buildings using high-strength steel are high-rise irregular structures, long-span bridges, factory structures, and high/low-voltage transmission towers.

By 2019, numerous high-strength steel structures have been erected both domestically and internationally. For example, the Sony Center in Berlin, Germany, uses S460 and S690 high-strength steel in its roof trusses, effectively reducing the self-weight of components; Grosvenor Place in Sydney, Australia, uses 690MPa high-strength steel in its ground-floor columns, reducing cross-sectional area and saving space in the underground parking lot; the Latitude Building in Sydney, Australia, uses high-strength steel as transfer trusses, lightening the structural self-weight; the Landmark Tower in Yokohama, Japan, uses 600MPa high-strength H-shaped steel columns, reducing cross-sectional area while ensuring structural load-bearing capacity; the Reliant Stadium in Houston, USA, uses 450MPa high-strength steel to achieve large vertical truss support structures that meet the requirements for a retractable roof; the National Aquatics Center in Beijing, China, uses Q460 steel for the inner columns of truss columns, reducing cross-sectional dimensions and facilitating better welding work.
