摘要
根据预应力FRP布加固混凝土梁的试验研究,描述了预应力FRP布加固混凝土梁的破坏类型;提出了减小预应力损失的一些措施;给出了预应力FRP布加固混凝土梁抗弯承载力的简便计算公式;计算结果和试验结果吻合较好。
The failure types are described according to the test beams strengthened with prestressed CFRP sheets. Measures of decrease prestress loss are provided. The simple and convenient formulas for flexural strength are proposed. The rusuhs from the fomulas generally agree with those from the experiment.
