The algorithm for calculating structural-nonlinear problems of structural mechanics is considered, combining the advantages of the finite element method in the form of a classical mixed method and the method of compensating loads. A study of the efficiency of the proposed algorithm was made for calculating problems of calculating a grillage with modeling piles as nonlinear elastic-malleable connections. The iterative efficiency of the proposed algorithm is analyzed taking into account the parameters of strengthening of connections under load
