摘要
通过3根用混凝土和外包钢板复合加固钢筋混凝土短柱和1根对比钢筋混凝土短柱的低周反复荷载试验研究表明,用混凝土和外包钢板复合加固,可有效提高钢筋混凝土短柱的抗震承载力。根据试验结果分析,提出了复合加固钢筋混凝土短柱的斜截面抗剪承载力公式。
In order to investigate their seismic behaviors, one contrasting reinforced concrete short column and three reinforced concrete short columns strengthened with concrete and exterior steel plate were tested subjected to low periodic reverse load. The composite strengthening with concrete and exterior steel plate can improve shear bearing capacity of reinforced concrete short column remarkably. Then the formula of shear bearing capacity is put forward for calculation of complex strengthening reinforced concrete short columns.
