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

description: X-ray computed tomography cross-sectional images of three FRP-confined concrete columns under five load levels are provided in this dataset. These 3D images can be visualized and processed in 3D image software, such as Avizo© 2022.1 software (Thermo Fisher ScientificTM). (https://www.thermofisher.cn/cn/zh/home/industrial/electron-microscopy/electron-microscopy-instruments-workflow-solutions/3d-visualization-analysis-software/avizo-materials-science.html) The dataset contains the following data files: 1. “Circular_S1_raw.am” X-ray Computed Tomography cross-sectional images (grayscales voxel format) of original circular specimen at load level 1 (zero-load level). 2. “Circular_S2_deformed.am” X-ray Computed Tomography cross-sectional images (grayscales voxel format) of deformed circular specimen at Load level 2 (24.5MPa). 3. “Circular_S3_deformed.am” X-ray Computed Tomography cross-sectional images (grayscales voxel format) of deformed circular specimen at Load level 3 (30.7MPa). 4. “Circular_S4_deformed.am” X-ray Computed Tomography cross-sectional images (grayscales voxel format) of deformed circular specimen at Load level 4 (34.8MPa). 5. “Circular_S5_deformed.am” X-ray Computed Tomography cross-sectional images (grayscales voxel format) of deformed circular specimen at Load level 5 (39.5MPa). 6. “Rounded_square_S1_raw.am” X-ray Computed Tomography cross-sectional images (grayscales voxel format) of original rounded square specimen at load level 1 (zero-load level). 7. “Rounded_square_S2_deformed.am” X-ray Computed Tomography cross-sectional images (grayscales voxel format) of deformed rounded square specimen at Load level 2 (19.3MPa). 8. “Rounded_square_S3_deformed.am” X-ray Computed Tomography cross-sectional images (grayscales voxel format) of deformed rounded square specimen at Load level 3(24.2MPa). 9. “Rounded_square_S4_deformed.am” X-ray Computed Tomography cross-sectional images (grayscales voxel format) of deformed rounded square specimen at Load level 4 (26.6MPa). 10. “Rounded_square_S5_deformed.am” X-ray Computed Tomography cross-sectional images (grayscales voxel format) of deformed rounded square specimen at Load level 5 (31.0MPa). 11. “Square_S1_raw.am” X-ray Computed Tomography cross-sectional images (grayscales voxel format) of original square specimen at load level 1 (zero-load level). 12. “Square_S2_deformed.am” X-ray Computed Tomography cross-sectional images (grayscales voxel format) of deformed square specimen at Load level 2 (18.5MPa). 13. “Square_S3_deformed.am” X-ray Computed Tomography cross-sectional images (grayscales voxel format) of deformed square specimen at Load level 3 (21.7MPa). 14. “Square_S4_deformed.am” X-ray Computed Tomography cross-sectional images (grayscales voxel format) of deformed square specimen at Load level 4 (19.3MPa). 15. “Square_S5_deformed.am” X-ray Computed Tomography cross-sectional images (grayscales voxel format) of deformed square specimen at Load level 5 (18.1MPa). 16. “Aggregates_circular.stl” Coarse aggregates surface geometry (triangulated surface elements format) and aggregates distribution information for the circular specimen. 17. “Aggregates_rounded_square.stl” Coarse aggregates surface geometry (triangulated surface elements format) and aggregates distribution information for the rounded square specimen. 18. “Aggregates_square.stl” Coarse aggregates surface geometry (triangulated surface elements format) and aggregates distribution information for the square specimen. 19. “Data_Displacement_and_strain.xlsx” Displacement vectors data and volumetric strain data for all the deformed specimens (circular, rounded square, and square). These data were obtained by the DVC analysis from the Avizo DVC module. <br> All data has been analyzed and presented in detail in the following paper: LI, Peng-Da; WU, Yu-Fei.
