DocumeNDT Uniaxial Compression Strength (UCS) tests – tomographic inspections dataset

DocumeNDT Uniaxial Compression Strength (UCS) Tests - tomographic inspections dataset This repository contains data from the sonic tomography inspections carried out during the cyclic Uniaxial Compression Strength (UCS) tests performed on six stone masonry walls at the laboratory of the Eduardo Torroja Institute for Construction Sciences (IETCC), from the Spanish National Research Council (CSIC). A first sonic tomography inspection was carried out before starting the test (C0) with no loading. Then, cycles of increasing loading were imposed to the wall. Two cycles are performed for each loading level. After reaching the maximum load in each cycle, the load is sustained and a sonic tomography inspection is carried out. The data set is structured in 3 levels of folders:<br> - At first level, the 6 folders correspond to the 6 tested stone masonry walls (Wall 1-6).<br> - At second level, for each wall, there are two folders and a readme file:<br> - The readme file contains specific details about the inspection, e.g., number of emission and reception points or maximum load corresponding to each cycle<br> - The folder 'Coordinates' contains two diagrams of the emission and reception locations in elevation<br> - The folder 'Loading Cycles' contains the sonic raw data recorded in each cycle<br> - At third level, for each loading cycle carried out during the UCS test, there is one folder. Each folder contains:<br> - The folder 'Coordinates' contains the exact coordinates of the emission and reception points in *.txt files<br> - The folder 'Emission raw signal' contains the recorded emission signal for each emission location<br> - The folder 'Reception raw signal' contains the recorded reception signal for each emission location Sonic data are presented in *.csv files, structured in columns. Each column correspond to a reception location. The values correspond to the voltage recorded. Specific details about the csv can be found in the readme file of each wall. The frequency of acquisition is 256000 samples/s. The detailed geometry of all walls (including the inner position of each stone) is publicly available and can be found in https://doi.org/10.5281/zenodo.7713700 The experimental results of the UCS test are also publicly available and can be found in https://doi.org/10.5281/zenodo.8341725.
