Accelerometer-Based Dynamic Health Monitoring Of The Swarnamukhi River Bridge With Seasonal Vibration Evaluation

Abstract

Ensuring the structural integrity of bridges is critical for public safety and cost-effective infrastructure management. This study proposes a real-time structural health monitoring system for the Swarnamukhi River Bridge using accelerometer-based vibration analysis. Accelerometers were strategically installed across the bridge to continuously capture dynamic responses under varying traffic loads and environmental influences.The collected data was analyzed through key performance indicators: Frequency vs. Load, Acceleration vs. Time, and Stress Distribution heat map. These graphical analyses revealed the bridge's dynamic behavior and helped identify zones with elevated stress or abnormal vibration patterns. Special emphasis was placed on seasonal variation, with a detailed analysis of vibration characteristics recorded during December. This temporal assessment provided insight into how environmental conditions affect structural performance over time.The system effectively detected early signs of potential structural anomalies related to traffic-induced vibrations, climatic factors, and possible seismic effects. By enabling timely and informed maintenance decisions, the approach enhances bridge longevity and operational reliability.The results confirm the viability of using low-cost, accelerometer-based monitoring systems for accurate, real-time structural health assessment. This method offers a scalable and replicable solution for monitoring other critical infrastructure assets, contributing to broader efforts in sustainable infrastructure management and disaster resilience.
