提出新的预应力碳纤维布加固混凝土柱锚固方法并研制了新的锚具、施工设备,通过试验研究、工程实际应用形成施工工艺,并提出了最佳控制张拉应力的公式。试验结果表明:用预应力碳纤维布加固混凝土柱,能充分利用碳纤维布强度,改善混凝土柱的结构性能,加固效果显著。
Proposed a new prestressed carbon fiber reinforced concrete column anchoring method and the development of new anchors, construction equipment, through the experimental study, the actual application of the project to form the construction process, and put forward the optimal control of tensile stress formula. The test results show that the prestressed carbon fiber reinforced concrete columns can fully utilize the strength of carbon fiber cloth and improve the structural performance of concrete columns, and the reinforcement effect is remarkable.
