| 摘 要： | 在完成6根预应力碳纤维板加固混凝土梁抗弯试验基础上,对我国现行《公路钢筋混凝土及预应力混凝土桥涵设计规范》中适用于预应力混凝土梁短期刚度的计算公式进行了修正并提出了适合于预应力CFRP板加固混凝土梁挠度计算的建议公式,应用建议公式对本文的试验梁以及国内外8根试验梁进行了对比计算。结果表明,计算值与试验值吻合较好。

| Abstract: | Based on the experiment of 6 concrete beams strengthened with prestressed CFRP plates,the calculation methods of short-term stiffness of prestressed concrete beams in China＇s＂Code for Design of Highway Reinforced Concrete and Prestressed Concrete Bridges and Culverts＂are modified,and formulas for deflection calculation of concrete beams strengthened with prestressed CFRP plates are suggested.The deflections of test beams and 8 existing specimens are calculated based on the proposed formulas.It is shown that the calculated values agree well with the experimental results. |
