description: The current work is dedicated to the analysis of deformations and the distribution of internal force in steel statically indeterminate constructions taking into account plastic deformations, on the basis of which an algorithm is developed for calculating these structures to determine their reserves of bearing capacity with subsequent employment in the design for super loads, in particular for fire grading constructions. The object of this research is the bar statically indeterminate steel constructions. The subject of this research is the limit equilibrium method and the algorithm for calculating bar systems using this method in software package. 
The tasks that were set in this work:
1. Finding of the methods of introducing plastic hinges in steel statically indeterminate constructions using different software systems;
2. The calculation of this design, taking into account plastic hinge, verification the calculation results in accordance with a similar task calculating by kinematic method of limit equilibrium; 
3. Development of an algorithm for calculating bar statically indeterminate constructions by the method of limit equilibrium in a software package;
4. The select of a practical example and the design calculation in accordance with the algorithm obtained in this research; 
5. Application of the calculation results of a practical example to determine degree of fire resistance;
6. The formation of some design models for the construction of practical example. Design for extreme climatic loading of these constructions in accordance with the developed algorithm.
The practical significance comes from obtaining an algorithm for calculating statically indeterminate steel structures taking into account the forming of a plastic state in its elements, it will allow taking into account the reserves of the bearing capacity of constructions when it is calculated for super loads and effects. 
The following results were obtained in the course of the research:
1. The criteria and methods for introducing a plastic hinge in the Ansys and SCAD software package have been formed; 
2. The steel behavior is analyzed taking into account the nonlinear effects of the action of plastic hinge in the construction;
3. An algorithm for calculating a statically indeterminate bar systems to determine the objective safety factor in the SCAD software package has been developed;
4. In accordance with developed algorithm, the statically indeterminate frame was designed for super loads with the conditions of some design accident situations, and designed for fire grading construction.
