| 摘 要： | 为了研究圆形钢套管加固钢筋混凝土柱的轴心受压承载力,进行了1根未加固的普通钢筋混凝土柱和3根圆形钢套管加固钢筋混凝土短柱在不同加固钢套管厚度下的轴心受压试验。试验结果表明：加固试件的强度和延性由于钢套管的约束均得到成倍的提高,并且随着圆形钢套管管壁的增厚,试件的承载力增大,延性变好。

| Abstract: | To study the basic mechanical performance of reinforced concrete short column strengthened by circular steel tube, a set of experimental work was carried out l contrast unstrengthened reinforced concrete column and 3 reinforced concrete columns strengthened by circular steel tube were tested under axial loading. The primary parameter of the strengthened columns was steel tube thickness. The results showed that the capacity and ductility of the strengthened columns grew up dramatically with the increase of the thickness of the steel tube. |
