The paper presents the process of a static load test on post-tensioned concrete industrial floor model in the first part and a numerical model of this task in the second part. The experimental model was designed as a cutout of a post-tensioned concrete industrial floor and the static load test was conceived as a simulation by loading the base plate of a heavy rack. The described static load test was part of a series of experiments focused on the problematics of interaction between concrete structures and subsoil and was realized at the Faculty of Civil Engineering, VŠB –Technical University of Ostrava.
