预应力CFRP板加固混凝土梁的抗弯性能试验
Flexural Performance of RC Strengthened Beam with Prestressed CFRP Plate
【摘要】 利用自行研制的碳纤维板(CFRP板)及其配套锚具,进行了预应力CFRP板加固混凝土梁的抗弯性能试验,对加固后梁的破坏形态、承载力、挠度等方面进行了对比分析。结果表明,预应力CFRP板加固钢筋混凝土梁能有效地改善梁的受力性能。
【Abstract】 The flexural performance of RC strengthened beams with prestressed CFRP plate is investigated experimentally based on the self-developed CFRP plate and supporting anchorage.The influence of failure type,the carrying capacity and the deflection are analyzed.The results indicate that the bending capacity of beams strengthened with prestressed CFRP plate is obviously improved.
