The article discusses the statistical analysis of the stresses and displacements obtained which are determined by conducting physical experimental studies and are based on the developed calculation methodology. Due to the fact that the model was tested in laboratory conditions, the scale factor was taken into account and the coupling equations for the transition from the model to nature were compiled. The degree of discrepancy between the actual and calculated values of loads is taken into account and the characteristics necessary for statistical analysis are determined. The relations of stresses and displacements are given, taking into account the inaccuracy of the calculation, deviations of internal force factors and errors in the rigidity of the nodes. The inaccuracy in determining the geometric parameters and the modulus of elasticity of the material is justified. Sufficient reliability of the results was obtained taking into account the complex of all adverse factors.
