SOME GEOMETRICAL BASES FOR INCREMENTAL-ITERATIVE METHODS (RESEARCH NOTE)

Finding the equilibrium path by non-linear structural analysis is one of the most important subjects in structural engineering. In this way, Incremental-Iterative methods are extremely used. This paper introduces several factors in incremental steps. In addition, it suggests some control criteria for the iterative part of the non-linear analysis. These techniques are based on the geometric of equilibrium path. Finally, some examples illustrate the capabilities of suggested approaches.
