Abstract

A typical case of a plane truss [1] is analyzed using a substructure analysis through the stiffness method proposed by Przemieniecki with the purpose of showing its advantages in engineering calculation when this strategy is used [2]. The results obtained are compared with the Ansysâ simulation software, in order to make important conclusions about the complexity reduction of the problem, and reduction of the cost when using computational techniques, since it is a topic of interest to structural designers in the research area. The substructure analysis using a finite elements software, such as Ansysâ, prove to have significant advantages on calculation used in research, since it allows to determine large structures using software that come with less features (such as the student version), in which structural division is possible, with the purpose of solving simultaneously several models from each divided part; hence, saving time and money is possible, since there is not a necessity for having full versions that come with more features for calculation.
