The calculated dependances refinement of the bearing capacity of metal-composite envelopes operating in stability

Based on the authors methodology the refinement of calculated values in accordance with available experimental data was performed. The above methodology correlates and aligns experimental and calculated values of the bearing capacity of multilayer envelopes operating under contraction conditions. In this respect the obtained calculated dependance enables to reduce statistical characteristics defining calculated and experimental variations estimate by the K-coeffi-cient. In such a way it allows to make more solid approach to the safety coefficient definition at the metal-composite structures design.
