| 摘 要： | 目的对纤维塑料加固与修复钢筋混凝土桥梁短柱在反复荷载作用下的滞回性能进行试验研究．方法试验制作了4根大比例的钢筋混凝土桥柱模型，采用GFRP和CFRP两种材料对试验柱进行加固，在恒定的轴压力下进行拟静力试验，其中1根试件在加固前经历一定程度的破损．结果分析结果表明纤维塑料加固与修复钢筋混凝土剪切短柱的不仅阻止了柱子的脆性剪切配合，而且使柱端峰值位移率达到了8％。结论纤维塑料加固与修复钢筋混凝土剪切短柱具有稳定的滞回性能、良好的延性及能量耗散能力，能有效的改善钢筋混凝土剪切短柱的抗震性能．

| Abstract: | An experimental study was carried out on seismic behavior of reinforcement concrete bridge short column retrofitted and repaired with fiber reinforced plastic.The total of four half-scale circular reinforced concrete columns were tested under reversed cyclic lateral force and constant axial load in double bending configuration.In order to provide a basis for comparison,one as-built column was tested.The other two column samples were tested after being retrofitted with GFRP and CFRP,respectively.The as-built column was repaired after failure.Experimental results showed the as-built column developed an unstable behavior and failed in brittle shear mode.The ductility and energy dissipation ability of all retrofitted and repaired samples were significantly improved. |
