| 摘 要： | 在确定预应力碳纤维板加固混凝土梁极限状态的基础上,分别给出预应力碳纤维板在梁底面粘贴和梁两侧粘贴进行加固时的设计计算方法。算例表明：该方法同非预应力加固方法相比可有效提高其抗弯强度及刚度,同时可减少碳纤维用量、节省工程总造价。

| Abstract: | Base on the determination of the ultimate state,the design calculation methods of the strengthened RC beams underside-bonded and side-bonded with prestressed CFRP plates are proposed respectively.Tests show that the prestressed CFRP plates can increase the bending bearing capacity and stiffness of concrete beam,and reduce the cost in CFRP and the whole project. |
