| 摘 要： | FRP片材加固混凝土梁的内力分析是工程中的重要问题。对FRP片材加固混凝土梁的内力分析采用了一种比较方便而且有效的方法—链杆法。计算了在均布荷载和集中荷载下,不同长度的FRP片材对混凝土梁内力的影响,得出了FRP片材的有效粘结长度。通过其他试验结果进行对比分析,验证了由链杆法求得的有效粘结长度的合理性。

| Abstract: | Analysis of internal force of Reinforced Concrete Beans is an important issue in engineering. Based on the internal force analysis of FRP Laminates reinforce concrete beams, a more convenient and effective method-rigid bar method is used in this passage. In this method, the effective bond length of the FRP Laminates can be obtained based on the influence of different length of FRP Laminates on the internal force of concrete beam, which is respectively calculated under the condition of the uniformly distributes load and the mid-span point load. Based on the comparison and analysis of test results and formulas made by other people, this effective bond length obtained by the rigid bar method is reasonable. |
