| 中文摘要: |
| 本文对2根再生混凝土试件进行低周反复荷载下的扭转试验，以粉煤灰取代水泥率为变化参数，研究在不同胶凝材料下再生混凝土弯剪扭复合受力构件的破坏形态、承载能力、滞回性能、耗能能力和延性性能等问题。研究表明，掺加15%粉煤灰的改性再生混凝土弯剪扭试件与普通再生混凝土试件相比，承载能力变化不大，延性指标和耗能能力基本相同。 |
| 英文摘要: |
| In this paper, two recycled concrete specimen are tested in torsion under the low frequency reversed load, with fly ash cement replacement rate as parameter of reinforcement. The failure features, bearing capacity, the hysteresis loops, energy-dissipating capacity of the two different gelled material specimen are investigated．The test and analyses show that the durability and energy-dissipating capacity of modified recycled concrete is slightly lower than that of members with recycled concrete. But the bearing capacity of modified recycled concrete member is slightly lower than the recycled concrete member. |
