Data for: Prestressing wire breaks in a bonded post-tensioned concrete beam

This dataset was collected at the Institute of Concrete Structures at Ruhr University Bochum. A brief description is provided below. The data were generated within the framework of the DFG Research Unit Concrete Damage Assessment by Coda Waves (CoDA). For further information on the Research Unit and related datasets, please refer to the community description.

The experiment focused on detecting prestressing wire breaks in an unloaded, bonded post-tensioned concrete beam using ultrasonic measurements. The dataset includes measurements recorded during the application of the prestressing force as well as during the generation of two wire breaks. Strain gauges installed on reinforcing bars and tendons served as reference measurements. Technical drawings of the specimen and the measurement setup are provided within the dataset. The data is structured as follows:

01 Original Documents

02 Raw Data

01 Material Properties

02 Associated data (strain from strain gauges, as .pkl files)

03 Ultrasonic signals, raw (.pkl files)
