This study focuses on the practical implementation of Operational Modal Analysis (OMA) with a minimalistic sensor setup, utilizing only a single accelerometer for data acquisition. By employing simulation techniques, the paper explores the identification of eigenfrequencies, a key parameter describing the natural oscillation frequencies of the bridge. This innovative methodology offers valuable insights into the bridge's response to dynamic forces, contributing to a more cost-effective and streamlined approach to structural health monitoring. The paper addresses the inherent challenges and limitations associated with employing a single sensor, showcasing the potential of OMA in scenarios where resource constraints or practical considerations limit the use of multiple sensors. The findings contribute to the broader field of structural dynamics and modal analysis, offering a nuanced perspective on the dynamic characteristics of suspension bridges in real-world conditions.
