This paper systematically analyzes the parameters of prestressed steel wire rope strengthened concrete beams using finite element software ANSYS, aiming to explore the influence of different reinforcement parameters on the flexural performance of the beams. Seven 2.4m concrete beam models with different reinforcement methods were established, including comparisons of factors such as the number of prestressed tendons, tensile control stress, and composite mortar protection. Through simulated loading tests, the deflection changes, stress distribution, and force characteristics of steel bars and steel strands were examined. The results indicate that prestressed reinforcement significantly improves the stress state of the beams: an increase in prestress can effectively reduce the tensile stress at the beam bottom and decrease the stress in the main reinforcement, but has no significant impact on structural stiffness. An increase in the cross-sectional area of prestressed tendons significantly enhances the beam's stiffness. Composite mortar protection, although increasing self-weight, reduces prestress loss and optimizes the stress distribution of the steel strands. In contrast, the steel plate bonding method fails to fully utilize its effectiveness under low loads and even increases the stress in the steel bars. Additionally, excessively high prestress values may lead to excessive tensile stress at the beam bottom, necessitating reasonable design in practical engineering. This study provides a theoretical basis and parameter optimization directions for the engineering application of prestressed steel wire rope strengthened concrete beams, verifying the effectiveness of this technology in enhancing bridge load-carrying capacity and extending service life.
