The light concrete (polystyrene concrete) composite slab with profiled steel sheeting was considered. In this slab, the flexible reinforcement (PMA-2) was used as strengthening. Previous experimental studies have shown that this slab has increased carrying capacity in 2.4 times compared with a similar slab without additional anchoring means. The finite element method (FEM) was used for a detailed study of the PMA-2 slab work and its components. The calculations of light concrete composite slab allowed to investigate the work of profiled steel sheeting, material contact, their bundles, as well as the work of the reinforcement and its influence on the stress-strain state parameters of polystyrene concrete and profiled steel sheeting. Comparison by FEM calculations with experimental data confirmed the accuracy and adequacy of the developed model for PMA-2 slab.
