To address the issues of corrosion and poor fatigue resistance of suspension rods in arch bridges, a method of using CFRP (Carbon Fiber Reinforced Polymer) material for suspension rods in arch bridges has been proposed. By comparing the mechanical performance of the arch structure and suspension rod components under different substitution principles, the equal area principle has been determined as the method for material replacement. Finite element software has been used to analyze and compare the static response of the structure between CFRP suspension rods and steel strand wire under different load conditions, showing that the difference in stress variation between the two materials is small and CFRP can effectively replace steel strand wire as the material for suspension rods in arch bridges. Furthermore, the stress on the suspension rods has been analyzed based on the short suspension rod effect. Compared to the replacement of the entire bridge structure, the replacement of individual suspension rods is found to be more effective and feasible for practical bridge applications. The application of CFRP material in suspension rod arch bridges has been promoted through actual engineering cases, providing new ideas for the development of arch bridges with suspension rods.
