| 摘 要： | 通过对混凝土结构加固后受力性能的分析,考虑二次受力问题,对纤维增强材料(FRP)加固混凝土梁进行了全过程分析;并研究了相关参数对FRP加固混凝土梁性能的影响.在此基础上,提出了一种简单、适用的极限抗弯承载力计算方法,并将具体实例的计算结果与典型的实验结果进行了对比,获得较为满意的结果,表明了该方法的准确性与合理性,对工程应用有一定参考价值.

| Abstract: | Based on the studies on the flexural behaviors of reinforced concrete members strengthened with FRP ,considering the initial loading level on the flexural strength ,the whole process of strengthened concrete beams under loads is done. And a proper ,practical calculation method for the flexural strength is suggested. The calculation results agree with the test results with considerable veracity and reliability. At last ,the effects of some parameters on the behaviors of strengthened beams are analyzed. |
