Abstract:Carbon fiber reinforced composite (CFRP) reinforcement has excellent properties such as light weight, high strength, corrosion resistance, and fatigue resistance, which makes it very suitable for making bridge ties for use in harsh operating environments. Due to the low transverse and shear strengths of CFRP tendons, a key issue in the fabrication of cables with CFRP tendons is the development of a suitable anchorage system. In this paper, a 7-wire CFRP bar bonded anchorage was developed for 7-mm diameter round CFRP bars. The static load test was carried out on the successfully developed 7-wire CFRP ropes, and the results showed that the stress strength of the successfully developed multifilament CFRP ropes was up to 2200MPa, and the anchorage anchorage efficiency was more than 95%.
