This paper presents an assessment of the impact of process parameters on the results of numerical analysis of a nonlinear computational scaffolding. The aim of this study was to determine the criteria for the selection of nonlinear analysis parameters, depending on the degree of structural nonlinearity of the structure model. On the basis of calculations made using Autodesk Robot Structural Analysis Professional 2011 it can be concluded that the results of analysis of a nonlinear boundary scaffolding anchored to a wall to a small extent depend on the parameters of an iterative process. The exception is the value of the residual force (unbalanced force) to be declared in the iterative process. The relative value referenced to the residual strength values of the forces in one increment should be 10-4. This value provides sufficient accuracy of calculations. In the calculated models, increasing the value of the residual forces can ensure convergence of the process , however, the results obtained in such a case differ significantly from other results obtained under the assumption of small values of residual forces.
