Additionally, the acoustic emission technique was used to monitor the progression of critical microscopic damage to CFRP rods in a bending anchoring system, which is closely related to the compression-shear fracture of CFRP rods within the anchor. The experimental results indicate that after the fatigue cycles of two million, the residual strength retention rate of CFRP rod was as high as 95.1% and 76.7% under the stress amplitudes of 500 MPa and 600 MPa, indicating good fatigue resistance. Moreover, the bending-anchored CFRP cable could withstand 2 million cycles of fatigue loading with a maximum stress of 0.4 \u03c3ult and an amplitude of 500 MPa without obvious fatigue damage. Moreover, under more severe fatigue-loading conditions, it can be found that fiber splitting in CFRP rods in the free section of cable and compression-shear fracture of CFRP rods are the predominant macroscopic damage modes, and the spatial distribution of macroscopic fatigue damage of CFRP rods reveals that the additional shear effect has become the determining factor in the fatigue resistance of the cable. This study demonstrates the good fatigue-bearing capacity of CFRP cable with a bending anchoring system, and the findings can be used for the optimization of the bending anchoring system to further enhance its fatigue resistance, which further promotes the application and development of CFRP cable and bending anchoring system in bridge structures.<\/jats:p>","DOI":"10.3390\/polym15112483","type":"journal-article","created":{"date-parts":[[2023,5,27]],"date-time":"2023-05-27T16:16:04Z","timestamp":1685204164000},"page":"2483","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":52,"title":["Experimental Investigation of Fatigue Capacity of Bending-Anchored CFRP Cables"],"prefix":"10.3390","volume":"15","author":[{"given":"Jingyu","family":"Wu","sequence":"first","affiliation":[{"name":"College of Civil Engineering, Shandong Jianzhu University, Jinan 250101, China"},{"name":"Key Laboratory of Building Structural Retrofitting and Underground Space Engineering, Shandong Jianzhu University, Ministry of Education, Jinan 250101, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yongquan","family":"Zhu","sequence":"additional","affiliation":[{"name":"Liuzhou OVM Machinery Co., Ltd., Liuzhou 545006, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4338-8944","authenticated-orcid":false,"given":"Chenggao","family":"Li","sequence":"additional","affiliation":[{"name":"Key Laboratory of Smart Prevention and Mitigation of Civil Engineering Disasters of the Ministry of Industry and Information Technology, Harbin Institute of Technology, Ministry of Education, Harbin 150090, China"},{"name":"Key Laboratory of Structures Dynamic Behavior and Control, Harbin Institute of Technology, Ministry of Education, Harbin 150090, China"},{"name":"School of Civil Engineering, Harbin Institute of Technology, Harbin 150090, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,5,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"814","DOI":"10.1080\/15376494.2021.2024927","article-title":"Mechanical properties of carbon\/glass fiber reinforced polymer plates with sandwich structure exposed to freezing-thawing environment: Effects of water immersion, bending loading and fiber hybrid mode","volume":"30","author":"Xian","year":"2023","journal-title":"Mech.
