Data for: Controlled Increase and Reduction of Prestressing Force in an Unbonded Post-Tensioned 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 monitoring controlled increases and reductions of prestressing force in an unbonded post-tensioned concrete specimen using ultrasonic measurements. Strain gauges installed on reinforcing bars and tendons served as reference measurements. Technical drawings of the specimen and the measurement setup are included in the dataset. The data is structured as follows: 01 Original Documents · Technical drawing 02 Raw Data 01 Material Properties 02 Associated data (strain from strain gauges, as .pkl files) 03 Ultrasonic signals, raw (.pkl files) Disclaimer: This data set contains data in the pickle data format. It is possible to construct malicious pickle data which will execute arbitrary code during unpickling. More information can be retrieved in the respective documentation (https://docs.python.org/3/library/pickle.html).
