This paper is devoted to the frameless coverings - special-type arch coverings extended to territories of Ukraine. This type of covering is essentially folded open type cylindrical ribbed shells that are based on an arched structural element - the thin-walled, cold-deformed profile. Based on accepted hypotheses and implementing structural nonlinearity and illustrating the possibility of progressive collapse, the algorithm of creating finite-element models of these coverings was constructed. During the research, to the verification created algorithm, the full-scale experiment was done. The stress-strain state of a block of the original structure and numerical model were analyzed. The components of the stress-strain state obtained in the research are presented in the form of a mosaic of the vertical deflections. Comparison of the calculated deflections and the experimental ones are shown. The qualitative congruence of the results proves the adequacy of the algorithm.
