| 摘 要： | 碳纤维材料嵌入式加固技术具有重大的应用价值和发展前景,在国外已成功运用于混凝土结构、砌体结构、木结构以及桥梁的加固。本文通过对11根试件梁的裂缝情况、荷载—挠度关系以及横截面刚度进行了研究分析,试验结果表明:考虑二次受力影响,在不同初始弯矩作用下CFRP布嵌入式加固能有效提高混凝土梁的抗变形能力。

| Abstract: | The strengthening method of using NSM FRP has great application value of civil engineering.It has been used to increase flexural and shear strength of deficient concrete, masonry,timber members and brigdes abroad. Based on research of the relationship of cracks, load-deflction and rigidity of the eleven RC beams,it is indicatied that the deformation performance of RC beams strenthencd by NSM CFRP sheets can be greatly improved. |
