| 中文摘要: |
| 对已受损并引起承载力和抗震性能不足的在役桥梁墩柱，急需进行加固补强。为此，本文探讨采用新型纤维增强复合材料(FRP)片材--芳纶纤维薄板(AFL)加固受损钢筋混凝土(RC)桥梁墩柱及其拟静力抗震实验方法，并对AFL加固受损RC柱实施了拟静力抗震实验。研究结果表明，采用本文所示AFL加固方法可有效提高RC柱的抗剪承载力、极限位移，改善其延性变形能力和滞回耗能能力。 |
| 英文摘要: |
| In service bridge pier column, which has been damaged and is lack of bearing capacity and seismic performance, is badly needed to be strengthened. In this paper, the strengthening of damaged reinforced concrete (RC) bridge pier column by using a novel fiber reinforced polymer (FRP)-aramid fiber laminate (AFL) and its pseudo static seismic performance testing method were studied, and its pseudo static seismic performance experiment was carried out. Results show that AFL strengthening method adopted in this paper can effectively improve the shear bearing capacity, limit displacement, ductile deformation capacity and hysteretic energy dissipation capacity of damaged reinforced concrete column strengthened by AFL. |
