Previous studies within former European Consortia of Earthquake Shaking Tables, have investigated and compared how well the different shaking tables of these consortia could execute the same task using identical elastic test pieces. It has resulted in a control enhancement at all the facilities. Being then necessary that similar comparison tests be developed with extension to non-linear behavior, the largest possible specimen, specifically designed for that purpose, was built and tested on three very different shaking tables. This test specimen was designed to reproduce the global non-linear behavior of a concrete building while being damaged during an earthquake, concerning a typical global stiffness reduction. This system, being able to simulate a sudden collapse or a progressive degradation, can reproduce, in a repetitive and accurate way, the same non-linear conditions. In the present paper the design of the test specimen is discussed and the results of the first tests are presented.
