Abstract: In order to solve the problem of interface end peeling of textile reinforced concrete (TRC) reinforced concrete beam structures, an end self-locking technique was proposed to anchor the TRC slabs at the bottom of the beams. Owing to the end anchorage provided by this technique, the TRC slab can continue to carry the load even if interfacial debonding occurs. However, compared with the fiber sheet, the fiber mesh has poor synergistic stress performance due to much larger gaps between the fiber bundles, and it is doubtful whether self-locking can be achieved without treatment. In order to improve the utilization of fiber mesh strength, this paper investigates the end-anchor self-locking enhancement effect through the end self-locking anchored fiber mesh tensile test. Measures such as increasing physical friction or adding chemical bonding to the fiber grid are taken to stretch it to failure. The failure modes and load-strain curves of each specimen are analyzed and compared, and a formula for calculating the bearing capacity of the fiber grid after enhancement is proposed. The results show that even if the size of the fiber grid is limited, the strength utilization rate of the fiber grid under end anchoring is increased by 60.66% by reinforcement measures, and the tensile bearing capacity of the three-layer grid can be similar to that of the fiber sheet. The application of the self-locking anchorage technology is expected to solve the problem of end-interface debonding in TRC-reinforced concrete beams, enhance the material utilization, and improve the strengthening effect. The proposed formula for calculating the bearing capacity after fiber mesh reinforcement can provide a useful reference for related engineering practice.
