The purpose of this research is to undertake a structural audit of the Mutha river bridge, which is located near Warje, Pune, on the Mumbai-Bangalore National Highway. In this study, a number of audit methodologies are combined to provide an overview of the bridge condition. To begin, a visual assessment of the bridge construction is conducted to identify any obvious defects in the members that require more care. The study considers traditional procedures such as the Rebound Hammer Test and the Ultrasonic Pulse Velocity Test. In the bridge structure, there are only a few ways for measuring deck displacement. As a result, an institutionally designed displacement sensors equipment is utilized in this investigation to determine the displacement in the deck of the bridge construction. Following a visual inspection, it was agreed to do a displacement test on all of the bridge decks. During the visual assessment, all of the deck beams were found to be damaged in some way. An 18.5 tons two-axel truck was driven across the bridge and displacement data were recorded at the same time for real-time loading. Then, compare the resulting displacement reading to the AASTHO-LFRD standard. The general condition of the bridge was assessed after completing the structural audit and evaluating the data, and the major areas that needed repairs were noted. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
