This article examines the issue of longitudinal and transverse bending beam. The author's task is to analyze the possibility of determining movements in the supercritical region using the software package. The solution of this type of problems is an important aspect of the non-linear analysis of beam systems. There were selected the most common in Russia, SCAD, LIRA-SAPR and LIRA 10, and the new for the Russian market SAP2000. The analytical solutions are presented. The analytical solutions are compared with the solutions obtained in the software package. Pictures of the results of displacements are presented, too. The results of research show the possibilities of software systems within the task. In writing the article there were used scientific works of domestic and foreign theorists of finite element method.
