X-ray computed tomography images for FRP-confined concrete with different cross-sectional shapes

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 “.am” format. These 3D images can be visualized by the 3D image viewer software, such as 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 original state of the specimen (zero-load level). In addition, the coarse aggregates’ surface geometry and their distribution information for all these three specimens are also provided in this dataset, labeled by “Aggreates_shapes (circular, rounded square, or square)”. These aggregate files are in “.stl” format (Standard Triangle Language), and many 3D software packages, such as 3D Studio Max, support this file format. This dataset also contains the DVC analysis results for all the deformed specimens labeled as “Data_DVC.xlsx” These DVC data were output from the Avizo DVC module.
