建筑用钢是中国钢材消费最大的品种,快速发展的建筑业为建筑用钢品种的开发和应用提供了广泛的市场.中国建筑用钢品种的开发和应用已经取得了巨大进步,但是建筑用钢的科研和应用技术开发仍然相对落后.这包括钢材新品开发能力和建筑应用技术水平较低;高强度高性能钢材的消费比例偏低;冶金标准和应用技术规范更新滞后等等.中国建筑用钢的技术含量较低,至今仍属于基础类、低档次钢种,科研开发资金投入相对不足.建筑用钢品种的技术指标尚需进一步完善,尤其是抗震性能指标的制定需要深入的研究.对目前建筑用钢中厚板、耐候钢、耐火钢以及钢筋品种的开发和国际上技术发展趋势进行了分析梳理.

The consumption of construction steel is the biggest in China. The rapid development of construction in-dustry provides a wide range of markets for the development and application of construction steel. The development and application of construction steel varieties has been made great progress. But compared with developed countries, scientific research and technology development for the construction steel is still relatively backward. This includes that lower level of development capabilities of new kind of steel products and applied technology; The low proportion of consumer applications for high-performance high-strength steel; Amendment cycle longer for national standards and technical specifications of construction steel and so on. The technical content of construction steel is relatively low, it belongs to the more basic, lower-end steel. The scientific research and development are relative shortage of capital investment. Variety of construction steel technology indicators still need to be further improved, especially seismic performance indicators is required depth study. Development and international technology development trends for the current plate steel, weathering steel, fire-resistant steel and steel rebars were analysis.
