摘　　要：通过3个FRP加固受损钢纤维高强混凝土框架边节点试件在低周反复荷载作用下的试验研究,探讨了FRP材料类型对加固受损钢纤维高强混凝土框架边节点的延性、耗能能力和刚度退化等抗震性能的影响。结果表明:粘贴玻璃纤维布的加固形式与粘贴碳纤维布的加固形式在加固效果上基本相同,且均优于粘贴混杂碳纤维布和玻璃纤维布的加固形式。By experimental investigating of the 3 FRP reinforced damaged steel fiber reinforced high-strength concrete frame exterior joints under the low cycle loading,it discussed the influence of FRP material types on seismic behavior of these damaged steel fiber reinforced high-strength concrete frame exterior joints.The result showed that,the reinforcing type of sticking glass fiber sheet was same as that of sticking carbon fiber sheet,and the two reinforcing types were better than that of the mixing the carbon fiber sheet and the glass fiber sheet.
