摘要 为研究再生混凝土直剪状态下的变形性能与损伤演变规律,以再生粗骨料取代率为变化参数,设计了33个再生混凝土试件进行直剪试验。试验观察了再生混凝土直剪荷载作用下的破坏形态,获取了再生混凝土直剪破坏全过程剪力-位移曲线,深入分析了精细化取代率对再生混凝土剪切模量、延性变形、能量耗散、损伤演变等性能的影响规律。结果表明:随着取代率的增加,再生混凝土的剪切模量减小,延性变形和能量耗散增加;取代率对损伤速率和损伤全过程曲线的影响不大,但对初始损伤时间有一定影响。基于抗剪强度试验结果,提出再生混凝土剪力-位移全曲线方程与再生混凝土损伤本构方程,所得计算结果与试验结果拟合较好。

Abstract: In order to study the deformation performance and the law of damage evolution of recycled concrete under the state of direct shear, a total of 33 recycled concrete specimens was designed for direct shear test with the replacement rate of recycled coarse aggregate as the change parameter.The failure pattern of recycled concrete under direct shear load was observed in the test, and the shear displacement curve of the whole process was obtained. The influence of the refined replacement rate of recycled coarse aggregate on shear modulus, ductile deformation, energy dissipation, damage evolution and other properties was deeply analyzed.The results show that with the increase of the replacement rate of recycled coarse aggregate, the shear modulus of recycled concrete decreases, ductility deformation and energy dissipation increase.The rate of substitution has little effect on the damage rate and the damage curve, but has some effect on the initial damage time.The shear-displacement equation and the damage constitutive equation is proposed based on the shear strength test results. The calculated results are in good agreement with the test results.
Key words:  recycled concrete    shear strength    deformation properties    damage evolution    energy dissipation    ductile deformation
