摘要

摘要: 当前，全球建筑基建行业加速向绿色低碳、高效集约、智能升级方向转型，钢结构作为现代基建的核心载体，是落实国家“碳中和”战略、推动建筑产业现代化的关键抓手。以Q690、Q960为代表的国产高强钢材，具备强重比优异、用材精简、低碳节能等多重优势，是新时期大型、大跨度、轻量化基建工程的优选材料。但长期以来，各国钢结构设计标准不统一、高强钢焊接工艺难度高、传统设计理论偏保守三大难题，制约了高强钢的规模化、国际化落地，其优异的工程价值与潜力未能充分发挥。为此，系统梳理了国家钢结构工程技术研究中心香港分中心在高强钢技术研发、工艺优化、国际标准对接、标杆工程建设等方面的核心成果，全面展现国产高强钢结构的创新突破与应用价值，展望行业未来发展方向，以期为国内钢结构产业升级、国产钢材出海推广提供重要实践参考。

Abstract: At present， the global construction and infrastructure industry is rapidly transforming toward green， low-carbon， efficient， intensive， and intelligent operations. As a core component of modern infrastructure， steel structures serve as a pivotal driver for implementing the “carbon neutrality” strategy and advancing the modernization of the construction industry. Chinese high-strength steel grades such as Q690 and Q960 offer superior strength-to-weight ratios， high material efficiency， and low-carbon and energy-saving benefits， making them the preferred choices for large-scale， long-span， and lightweight infrastructure projects in the new era. However， for a long time， three major challenges have hindered the large-scale and international application of high-strength steel： the lack of unified international design standards， the technical complexity of welding high-strength steel， and conservative design methods. Consequently， its exceptional benefits and potential have not been fully realized. This paper systematically reviews major achievements， of the Chinese National Engineering Research Center for Steel Construction （Hong Kong Branch； CNERC）， including research and development， optimization of manufacturing processes， alignment with international standards， and the construction of landmark projects. This paper comprehensively shows the innovative breakthroughs and engineering applications of Chinese high-strength steel structures， and looks ahead to the future of the steel industry， so as to provide valuable experience for the upgrading of the Chinese steel structure industry and the export of Chinese steel structures worldwide.
