Hybrid and pseudo-dynamic experimental tool boxes

Pseudodynamic or PSD testing with substructuring technique is a highly relevant approach to capture the dynamic failure mechanisms of a structure. It allows to realistically test a structure subject to an earthquake with an accessible experimental equipment. Only the critical part of the structure is physically tested while the rest of it is numerically computed. We propose in this contribution to apply such a PSD testing with substructuring to damaging structures, where the nonlinear behaviour is represented by an advanced damage model. The challenges today are to take into account real time in a hybrid test, making it possible to introduce the effects of time on the response of the material. The coupling with the calculation therefore requires a very efficient numerical analysis capability. The proposed PhD project will take into account a non-linear numerical model by reduced order model (ROM) techniques, coupled with real-time experimentation.
