钢筋混凝土墩柱加固滞回耗能试验

Energy-intensive Test of Reinforced Concrete Pier Column Reinforcing

针对钢筋混凝土墩柱因延性不足而常在地震灾害中遭到破坏的现象,分别采用玻璃纤维、芳纶纤维和环向箍筋3种不同材料对模型墩柱进行加固,通过拟静力试验,分析滞回耗能,从而研究其抗震延性,得出:3种不同材料的加固方法对墩柱抗震性能有不同程度的改善,其中芳纶纤维加固的墩柱平均耗能系数最大、抗震性能最好。

As tensibility, glass the reinforced concrete pier columns are often destroyed by earthquake because of the lack of exfiber, aramid fiber and round hoop are used to reinforce the pier column. The quake-proof extensibility s researched by doing static load test and analyzing the energy-intensive. A conclusion is made as below： Those materials improve the performance of quake-proof to some extent, the best of the three is aramid fiber
