Application of High-Performance Fiber-Reinforced Materials in the Reinforcement of Old Bridge Structures
With the acceleration of urbanization process and the increase of transportation load,many old bridge structures are gradually faced with serious safety risks and service life problems.In this paper,taking the steel structure of the old bridge as the research object,we systematically analyze the reinforing effect of high-perfor-mance fiber-reinforced materials.In the simulation analysis of the reinforcement axial bearing components of high-performance fiber-reinforced materials,we should pay attention to the material structure,including the per-formance characteristics of steel and combined rubber.The appropriate cell type is chosen to accurately simulate the material behavior and to establish contact relationships within the components.Make fine mesh division to en-sure calculation accuracy,and set reasonable boundary conditions and loading methods.After completing the above steps,the results were analyzed to evaluate the reinforcement effect.It is also necessary to study the numer-ical simulation of high-performance fiber-reinforced materials,establish a precise finite element model,and veri-fy the model through experimental data or other verification means.Through the parameter analysis,the influence of different factors on the reinforcement effect is discussed,and the reinforcement design is optimized,so as to improve the bearing capacity and structural stability of the old steel bridge.With the help of accurate finite ele-ment model and experimental verification,the optimal design of HPFRM reinforcement scheme can effectively ex-tend the service life of the bridge and enhance its safety,laying a solid foundation for further improving the sta-bility of the bridge structure.
