Abstract : Pipelines play a vital role in ensuring the efficient and secure transportation of water, making their performance to keep the water continuously going vital. This research explores the influence of air valves on the localized damage and overall functionality of the pipelines. Air valves are critical components that help stabilize pressure and prevent vacuum formation. However, their installation can introduce structural weaknesses in localized areas. The study employs FEM modeling alongside field data from a collapsed bridge to assess the performance and damage in the vicinity of air valves. The findings reveal that strategic redesigns, such as optimizing air valve placement and reinforcing surrounding areas, can significantly enhance performance while mitigating local damage. Additionally, the research highlights the effectiveness of repair methods in increasing pipeline resistance to bending stresses and compares various repair and design approaches, providing new insights into mitigating structural damage in aqueduct bridges. This study addresses a critical gap in the literature, offering a thorough approach to understanding and addressing air valve-related damage in engineering.
