Dataset for: Operational Dynamic Performance of an Aging Reinforced Concrete Bridge under Increased Heavy-Traffic Demand

This repository contains the operational monitoring data and analysis scripts used in the study "Operational Dynamic Performance of an Aging Reinforced Concrete Bridge under Increased Heavy-Traffic Demand: Insights from Modal Identification and Displacement Monitoring". The dataset includes: Raw acceleration records (.mseed) from 217 independent vehicular events recorded on the Pindo River bridge (Ecuador). Processed displacement signals obtained through baseline correction and double numerical integration. Python scripts used for signal processing, automated filtering, and spectral analysis (Fast Fourier Transform) to identify the natural frequencies of the structure. Engineering plots illustrating dynamic envelopes and average frequency spectra. This data supports the findings regarding the operational response of the aging bridge under varying traffic intensities and provides the baseline for structural health monitoring.
