An analysis of the stress-strain state of one of the oldest types of floor structures, namely, masonry vaults supported by steel beams (in some cases, by steel rails), the so-called Monnier vaults, was carried out. As a rule, the indicated constructive solution of ceilings was used in ceilings above basements and has been preserved to this day in Moscow, St.Petersburg and other cities. The analysis was performed for one of the buildings located on Tverskaya Street in Moscow. Taking into account the specifics of the stress-strain state of the structures under consideration, taking into account the presence of damage in some cases, the analysis was carried out in the Lira CAD 2019 (R2) program, in which the material parameters were set according to the 14 piecewise linear law. Based on the results of the calculation, the values of deflections, the maximum values of the forces Nx, Ny, Qx, Qy, Mx, My, the principal stresses in the lower and upper layers of the roof σ1 and σ2, the forces Qz and My in the steel beams of the roof, taking into account their joint work with the vault, were obtained. Design models for laying vaults in linear and non-linear formulations have been built and analyzed. At the same time, the results of a comparison of various models showed that in metal beams with a passive load from the vault without its inclusion in the work, large stresses arise, and they may lose their bearing capacity. The bearing capacity of steel beams was evaluated for two groups of limit states, taking into account their joint work with vaults, as well as the bearing capacity was checked for local stability, taking into account the operation of the vault.
