The objective of this work is to investigate the support-specimen interaction during the compressive experimental testing of stiffened plates. The interaction is analyzed employing the nonlinear Finite Element Method using the commercial software ANSYS. The connection between the stiffened plate and testing supports is modelled with the use of contact elements, where several possible interaction scenarios are investigated, and their impact on the ultimate strength is evaluated. The sensitivity of the modelling of the testing support structure to the boundary conditions as generated by the finite element model and the structural behavior of stiffened plates during the test are also investigated, and several conclusions are derived.
