摘要 以重度受损钢筋混凝土柱为研究对象,研究其经加固修复后斜截面的抗剪性能。将重度受损钢筋混凝土柱根部塑性铰区范围内的混凝土用高强度灌浆料置换,并环向粘贴单向碳纤维布对试件进行斜截面抗剪加固,通过对其施加低周期反复荷载,观察其斜裂缝开展情况及裂缝宽度,分析其斜截面受剪承载力,与未做加固修复的试件进行对比,研究加固后试件的抗剪性能。其加固后试件受剪承载力有明显提高。 Taking serious damaged reinforced concrete columns as the research objects, it is researched the shear strength of repaired columns. The concrete of columns within the scope of the plastic hinge aera is replaced by grouting material and the inclined section of the columns are strengthened with unidirectional CFRP. According to the low-cyclic and repeated load , the diagonal crack development and crack width of the columns are observed and the inclined section baring capacity of the columns is analyzed. The results are compared with the performance of the contrast test piece in order to study the shear performance of the repaired and strengthened specimens, the shear bearing capacity of the repaired and strengthened specimens is signifi cantly improved.
