“…Under the three anchoring lengths, the average tensile strength of the specimens with a bonding media thickness of 3 mm is slightly higher than that with a thickness of 4 mm, and the difference is about 10%. The reason may be that when the resin layer is thicker, its deformation may also increase, leading to a decrease in anchoring performance [ 17 , 20 , 21 ]. When the bonding media thickness is 3 mm and 4 mm, the anchoring performance is also basically the same, but a minimum thickness of 3 mm needs to be ensured.…”

“…To connect to other structure members, anchorages are used for FRP tendons/cables. A large number of tests on anchorage systems of FRP tendons have been conducted [ 1 , 3 , 6 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 ]. The commonly used anchoring methods for FRP tendons mainly include bonded anchoring, mechanical anchoring, and composite anchoring [ 6 ].…”

FRP tendons and cables are increasingly being used in civil engineering structures due to their high strength-to-weight ratio and corrosion resistance. The bond anchorage factors, which characterize the bond strength between the FRP tendon/cable and the surrounding materials, play a critical role in determining the overall performance of the system. In this study, a series of tensile tests were conducted on FRP tendons/cables with different bond anchorage factors to evaluate their load-carrying capacity, load–displacement curve, and strain distribution. The study considered different types and surface shapes of FRP tendons/cables, and determined the influence of anchoring length, bonding medium type, and bonding medium thickness on the performance. The strain distribution of FRP tendons/cables at the anchorage end gradually increased along the loading section to the free end. A stress analysis model of the anchoring section was proposed and found to be consistent with the test results.

“…Various types of tendons exist, with notable distinctions between steel tendons and Fiber Reinforced Polymer (FRP) tendons. The latter, in turn, encompasses diverse materials such as Carbon, Glass, Aramid, and Basalt, referred to as CFRP, GFRP, AFRP, and BFRP respectively [ [2] , [3] , [4] , [5] , [6] ].…”

“…Fang et al [13] proposed a multi-rod carbon-fiber-reinforced polymer (CFRP) anchoring system using ultra-high performance reactive powder concrete as a bonding medium and applied it to Aizhai Bridge in China successfully. However, long-term exposure to stress, condensate, temperature difference, acid, alkali, and other complex environments will gradually reduce or even lose the bond between tendons and adhesive [14,15]. The mechanical anchorage relies on the friction between the cable surface and the inner surface of the anchoring member to balance the cable tension.…”

Carbon-fiber-reinforced polymer (CFRP) is a type of composite material with many superior performances, such as high tensile strength, light weight, corrosion resistance, good fatigue, and creep performance. As a result, CFRP cables have great potential to replace steel cables in prestressed concrete structures. However, the technology to monitor the stress state in real-time throughout the entire life cycle is very important in the application of CFRP cables. Therefore, an optical–electrical co-sensing CFRP cable (OECSCFRP cable) was designed and manufactured in this paper. Firstly, a brief description is outlined for the production technology of the CFRP-DOFS bar, CFRP-CCFPI bar, and CFRP cable anchorage technology. Subsequently, the sensing and mechanical properties of the OECS-CFRP cable were characterized by serious experiments. Finally, the OECS-CFRP cable was used for the prestress monitoring of an unbonded prestressed RC beam to verify the feasibility of the actual structure. The results show that the main static performance indexes of DOFS and CCFPI meet the requirements of civil engineering. In the loading test of the prestressed beam, the OECS-CFRP cable can effectively monitor the cable force and the midspan defection of the beam so as to obtain the stiffness degradation of the prestressed beam under different loads.
