Load testing of bridges is a critical process to evaluate their structural integrity and performance under expected traffic conditions. This method involves applying controlled loads, either static or dynamic, to assess the bridge's ability to withstand various stresses and strains. Load testing helps identify any potential weaknesses, verify design calculations, and ensure compliance with safety standards. It can also reveal the real-world behavior of the bridge, including deflections, vibrations, and stress distribution. Regular load testing is essential for maintaining the safety and longevity of bridges, particularly those subjected to heavy or increasing traffic loads. By providing accurate data on the bridge's condition, load testing supports informed decision-making for maintenance, repairs, or upgrades, ensuring the continued safety and reliability of vital infrastructure. This book unravels the recent studies in the field of load testing of bridges. It traces the progress of this field and highlights some of its key concepts and techniques. The readers would gain knowledge that would broaden their perspective about structural engineering and bridge construction.
