简要介绍了目前有关超高强钢筋和超高强钢筋用于钢筋混凝土结构的国内外的研究与应用。研究表明,超高强钢筋用于钢筋混凝土结构,特别是作为箍筋可以有效提高其抗震性能;超高强钢筋与高强混凝土组合不仅能更好地发挥两者的性能还可有效解决高强混凝土的脆性,这为减少材料的使用,从而节约资源、节能减排提供了有效的途径。
The current research and application of ultra-high strength steel bars and ultra-high-strength steel bars used in reinforced concrete structures are briefly introduced. The research shows that the ultra-high strength steel used in reinforced concrete structures, especially as a stirrup, can effectively improve its seismic performance. The combination of ultra-high-strength steel and high-strength concrete can not only make better performance of both but also effectively solve the brittleness, This provides an effective way to reduce the use of materials, thus saving resources and saving energy.
