| 摘 要： | 碳纤维(CFRP)以其优异的性能成为土木工程领域极具应用前景的新型建筑材料,但CFRP筋在应用中遇到的最大难点就是锚固问题.在对传统夹片式锚具进行改进的基础上,对不同锚杯长度和锚杯内壁倾角的新型夹片式锚具进行了疲劳性能试验研究.试验结果表明,该类锚具具有良好的动力抗疲劳性能;锚杯内壁倾角一定时,锚杯长度越大,锚具组装件的疲劳性能越好.

| Abstract: | Carbon Fiber Reinforced Polymers(CFRP),which was of excellent properties,has presented particular interests for civil engineers all over the world.However,the disadvantage for CFRP tendons to be used is how to anchor the CFRP tendons and to maintain the post-tensioning force during the service life of the structures.A series of fatigue tests were done for the developing a new types of anchorage system for CFRP tendon based on the ameliorated conventional wedge-type anchorage system,the influence to anchor p... |
