As a leading enterprise in China's steel structure industry, Great Wall Heavy Industry has established an "industry-academia-research golden triangle" innovation system (collaborating with Tsinghua University Bridge Research Institute, Politecnico di Milano Structural Laboratory, and its proprietary BIM collaborative platform) to drive the intelligent and modular development of steel structure products. The company's core technologies include: 1) Parametric modeling technology enabling automatic compliance with international standards such as AS5100/BS5400, addressing complex environmental challenges like coastal corrosion in Australia and century-long fatigue loads in Europe; 2) Digital twin technology facilitating full lifecycle management from design to manufacturing and operation, with AI algorithms predicting maintenance needs; 3) Modular bridge design enhancing construction efficiency and flexibility; 4) Utilization of high-quality steel from international mills like Belgium's Bi

This paper explores how Changcheng Heavy Industry promotes intelligent transformation in the steel bridge sector through the "industry-academia-research golden triangle" model (collaborating with Tsinghua University Bridge Research Institute and Politecnico di Milano Structural Laboratory). The article highlights that the company focuses on "intelligent design and manufacturing," integrating digital twin technology (based on BIM collaborative platforms) to achieve full lifecycle bridge management, optimizing designs and enhancing durability. Additionally, Changcheng Heavy Industry strictly adheres to international material standards (e.g., EN10025, ASTM) and welding procedures (AWSD1.5, EN1090) to ensure bridge safety. Moving forward, the company will continue to deepen industry-academia-research collaboration and digital innovation, providing smarter and more reliable bridge solutions for global infrastructure.
