外包粘钢抗震加固钢筋混凝土墩柱的研究进展

总结了国内外对外包粘钢加固钢筋混凝土墩柱研究的进展,已有的研究表明外包粘钢加固能有效地提高墩柱的承载力、延性和耗能能力,改善墩柱的破坏模式及变形能力,具有良好的抗震性能。最后,提出了一些当前研究的不足及需要深入研究的问题。

The Research Development of the Seismic Strengthening of Reinforced Concrete Columns with External Bonded Steel

The research development of reinforced concrete columns strengthened with external bonded steel made by domestic and foreign scholars were summarized in this paper.Existing studies have shown that the method not only can enhance effectively the carrying capacity,the ductility and the energy dissipation capacities of concrete columns but also improve deformation and failure mode of columns,so as to have favorable seismic performances.Moreover,a number of deficiencies in current research and some questions for future study were also suggested.
