Annotation: There are examined analytical and numerical simulation of a high-pressure gasholder deflected mode of low-alloyed steel using the up-to-date programs Lira 9.4 and Cosmos-Works. Using the methods of structural mechanics and theory of strength of materials, the gasholder most rational structural form and geometrical parameters were revealed. Numerical results obtained by the programs Lira 9.4 and Cosmos-Works were compared to fix their reliability. It has been proved that the models created by the both programs give conservative values of the equivalent stresses in comparison with an analytical model. Numerical results obtained with the help of Cosmos-Works have four-time as little the relative error than the results obtained with the help of Lira 9.4 in comparison with the results of the numerical simulation, and thus are more reliable.
