The article presents the evaluation results of load-bearing capacity exhaustion of steel-concrete slabs under concentrated and distributed short-term loading. The authors investigate the performance peculiarities of square, circular, and octagonal samples. The results of the experimental research were verified by comparison with the results of finite element modeling in the LIRA-SAPR software package. The obtained results proved the theoretical equations that allow to define the load-bearing capacity of steel-concrete slabs during their destruction over the cross-section and along the contact of sheet reinforcement with concrete. It is recommended to find the required intensity of sheet reinforcement anchoring from the condition of equality of ultimate loads. The authors provide further FEM analysis of square slabs to evaluate the impact of anchor spacing, the thickness of the steel sheet, and supporting conditions of slabs on their load-bearing capacity.
