For more accurate calculation of structure it is required to apply loads in the process of its construction instead of load application after structure has taken its final form. This action is necessary in order to observe changes in the stress-strain state of the structure under study. This circumstance is important for the massive hydraulic structures, such as hydroelectric dams. It is required to determine tensions, deformations and displacements in solving the building-up tasks. It is necessary to consider the problem for constructions of linear and nonlinear materials and check the principle of superposition on which the method of solving nonlinear problems is based. Also it is necessary to consider the solution of finite element schemes with the help of various iterative methods, such as the method of additional loads and the method of variable.
