The article considers the application of the method of discrete elements with generalized unknowns for calculating rod systems located in an aggressive environment. The object of research was a spatial rod truss. The basic formulas for determining the reactions of bonds at unit displacements are shown. The equation of displacements for an arbitrary node is derived. The system of equations was solved in partial finite differences. Reactions from external loads were represented as trigonometric series. An algorithm for calculating a statically indeterminate spatial truss by the method of discrete elements with generalized unknowns under the action of an aggressive environment is given. As a result of the calculation, the values of node point movements are obtained.
