X-ray computed tomography images for FRP confined concrete

The dataset contains the X-ray computed tomography cross-sectional images of three FRP confined concrete columns under five load levels. All these CT-scanned 3D images are in “.<em>am</em>” format, and these 3D images can be visualized by the 3D image viewer software Avizo (https://www.thermofisher.cn/cn/en/home/electron-microscopy/products/software-em-3d-vis/avizo-software.html?SID=srch-srp-AVIZO). These data files were labeled by the cross-section shapes (circular, rounded corner, and square) followed; by the load levels (S1 to S5), where “S1_raw” represents the zero-load level. In addition, the coarse aggregates’ surface geometry and their distribution information for all these three specimens are also provised in this dataset, labeled by “Aggreates_shapes (circular, rounded corner, or square)”. These aggregate files and are in “.stl” fromat (<strong>S</strong>tandard <strong>T</strong>riangle <strong>L</strong>anguage), and this file format is supported by many 3D software packages. This dataset also contains the DVC analysis results for all the deformed specimens labeled as “Data_DVC.xlsx”, and these DVC data were output from the Avizo DVC module.
