Abstract
The paper presents preliminary results of theoretical and experimental analysis of the resistance of construction panels at compressive loading. Panels, made on the base of polystyrene foam in combination with thin-walled cold-formed elements, should be used as a load-bearing wall panels for simple and small structures. Investigated panels, with dimensions 1.0x2.5x0.15 m, are formed by six thin-walled elements of U-profile with a thickness of 0.8 mm, which are stabilized by glued polystyrene board EPS 100 S, 150 mm thick. Sufficient number of strain gages and inductive sensors were used for the experimental measurement of strains and deflections. Strain gauges and inductive sensors were both-sided suitably located on each tested panel. Spatial calculation model was created within software SCIA and ANSYS. Geometrically nonlinear analysis was used for the numerical solution. Based on the numerical and experimental results, the efficiency of polystyrene boards on the stability of used thin-walled steel elements was determined.
