Collection of experimental concrete test data for model calibration and validation

In order to calibrate and validate different constitutive models which have been developed to describe behavior and failure of concrete, experimental data of sufficient quality covering different experimental setups are required. Unconfined and confined compressive tests, direct or indirect tension tests are desired to well calibrate concrete models. To reproduce the damage evolution and the softening behavior, also post-peak data have to be acquired. This paper provides a comprehensive set of concrete test data, cast from the same batch in order to promote the application of advanced concrete models. Flexure tests of four sizes, confined and unconfined compression tests, as well as Brazilian splitting tests of five sizes, and loading and unloading data included in the database (http://www.baunat.boku.ac.at/comprtest.html) are available for the model development, calibration, and validation. For all specimen sets, the nominal stress-strain curves and crack patterns are provided.
