Progress in Digital Construction of Steel Tubular Trusses

Digital construction of steel tubular trusses has achieved full BIM application, automatically generating component models through parametric design, and integrating IoT technology to control manufacturing errors within ±2mm. Pilot cities such as Suzhou are promoting intelligent construction equipment, increasing the automation rate of truss welding to 65% and shortening the construction cycle by 30%.

Modern technology places greater emphasis on the integration of digital twins and AI. For example, the Jarvis Hawkeye platform uses panoramic cameras and AI algorithms to achieve real-time monitoring and early warning of construction progress and quality. The Central Plains High-speed Railway Port project adopted intelligent lifting technology to complete the precise installation of a giant steel tubular truss with a diameter of 102 meters and a weight of 1365 tons, setting a technological milestone.
