Data To: Efficient Approach to Measuring Strength and Deformation of Passively Confined Concrete

Published: 17 January 2022| Version 1 | DOI: 10.17632/pvtwhy3fz5.1


Processed experimental data on the behavior of concrete cylinders 100x200 mm with aluminum rings to generate passive confinement subjected to monotonous uniaxial compression. The data contain the response (axial stress, axial and lateral strain) for all four experimental setups (8 or 12 rings, ring thickness 2 or 3 mm) and the uniaxial tension test of aluminum. Specimen designation and geometry: 8R t2 = 8 rings, ring thickness 2 mm 8R t3 = 8 rings, ring thickness 3 mm 12R t2 = 12 rings, ring thickness 2 mm 12R t3 = 12 rings, ring thickness 3 mm Description of the content: axial_average = stress-strain relationship for all specimens presented individually. Axial deformation is measured using extensometers over a 100 mm length and the average value is presented. axial_average = statistically processed stress-strain relationship (details above) axial_lateral = stress-strain and axial-lateral strain presented individually for all specimen, axial strain is the average of extensometers with 100 mm length, lateral strain is the average of DIC measurement on rings in the central 100 mm long part. The length of DIC extensometer is 60 mm (projection). aluminum_detail, aluminum = stress-strain relationship for aluminum AW6060 T66 used for the circular rings. The tests are done on prismatic coupons cut from a square hollow section in the perpendicular direction to its longitudinal axis. Other data will be provided on request.


Steps to reproduce

This dataset contains processed experimental data as presented in the original research paper. Each folder contains the data files (*.dat) with tab-separated columns. The data can be plotted in Gnuplot using the definition file (*.gnu) which will produce an image in *.pdf with the same name (also attached).
