| description | This study numerically investigated retrofitted transmission towers subjected to static wind loads using nonlinear pushover analysis, emphasizing enhanced structural resilience and safety. Transmission towers are critical infrastructure that must withstand extreme wind conditions. However, aging structures and increasing load demands necessitate effective retrofitting strategies. The nonlinear pushover analysis employs advanced finite element modeling to simulate the nonlinear inelastic behavior of towers under incremental static wind loads until failure. Six retrofitting methods are presented and compared to identify the most effective retrofitting approach for the considered tower. The findings reveal that retrofitting significantly improves the capacity, ductility, and stiffness of transmission towers under static wind loads, delaying buckling and failure. The proposed retrofit method enhances tower capacity by at least 10% compared to the non-retrofitted configuration. |
