摘要
通过10块不同钢筋腐蚀率、100%再生骨料取代率的再生混凝土简支板静力试验,研究腐蚀钢筋再生混凝土板破坏形态、承载力及跨中挠度。根据试验结果研究了再生混凝土板的承载力和挠度与钢筋腐蚀率的关系,并提出了腐蚀钢筋再生混凝土板承载力计算公式。
Based on the static experiments of 10 simple-supported recycled concrete slabs with different steel corrosion degree and 100% recycled aggregate,the failure mode,bearing capacity and mid-span deflection of recycled concrete slabs with corroded reinforcing bars were investigated.According to the results,the relationships between bearing capacity and deflection of recycled concrete slabs and steel corrosion degree were established.The calculation formula for bearing capacity of recycled concrete slabs with corroded reinforcing bars was put forward.
