The company Tehnoplast profili d.o.o. from Zagreb, in cooperation with the Faculty of Civil Engineering University of Rijeka and the company Palijan d.o.o. from Zagreb, is conducting a scientific research project dealing with buildings of near-zero energy produced in an industrial way. The construction system of these buildings consists of ceiling and wall panels, which are integrated into the building’s construction system. The structural wall/ceiling panels consist of external gypsum-fibreboard, thin-walled steel structure in the panel core and polymer foam in between. To enable the practical application of the innovative wall/ceiling panel system as a load-bearing structural element, the design model based on the comprehensive experimental and numerical investigation must be defined. In the research presented in this paper the performance of the composite wall/ceiling panels and the steel core wall/ceiling structure during out-of-plane to failure tests is shown.
