CREATE Center: Hydrodynamic Properties from Free-Vibration Response of a Prestressed Girder Bridge Model

The data archive associated with the CREATE UTC report: Assessment of Hydrodynamic Properties from Free-Vibration Response of a Prestressed Girder Bridge Model, contains datasets, supporting documentation, and analysis scripts required to reproduce the results presented in this report. The archive is intended to support transparency, reproducibility, and secondary use of the experimental results by researchers and practitioners studying fluid–structure interaction in bridge systems. The archive is organized into a structured directory system within a single zip file that contains several categories of data products generated during the study: 1. Experimental DataThis directory contains the unprocessed data files collected directly from the instrumentation system during laboratory testing. These datasets include time-series measurements used to characterize bridge vibration behavior. The raw data are stored in non-proprietary formats ( TXT) to ensure long-term accessibility and compatibility with multiple analysis platforms. 2. Processed and Reduced DataProcessed datasets derived from the raw measurements are provided in separate directories. These files include filtered records, identified modal parameters, calculated damping ratios, and estimates of hydrodynamic added mass. The processing steps used to generate these datasets are documented in the accompanying metadata files and analysis scripts. 3. Test Configuration and MetadataThis directory contains documentation describing the experimental setup, including bridge geometry, sensor locations, and conditions during testing. Metadata files describe the structure and contents of each dataset, including variable names, units, sampling frequencies, and data formats so that future users can correctly interpret the measurements. 4. Analysis Scripts and Processing CodeScripts used for signal processing, modal identification, and damping estimation are included in the archive. These scripts were developed primarily in MATLAB and are provided to allow reproduction of the data processing workflow and verification of the reported results. 5. Figures and Derived ResultsData files used to generate the tables and figures presented in this report are included in the archive. These datasets correspond to the processed results used to quantify added mass coefficients, damping ratios, and frequencies for the bridge system tested. 6. Documentation and Read-Me FilesA comprehensive README document is included at the root of the archive describing the overall dataset structure, file naming conventions, software requirements, and instructions for reproducing the analyses.
