Finite element analysis is used to estimate the displacements and forces present in each element of a structure. This type of analysis is time consuming in pre-processing, processing, and post-processing. It also incurs considerable computational costs. A simplified methodology is therefore required to reduce design time considerably. The research involved the development and application of an experimental methodology and a simulation, using Ansys Research software’s LS-DYNA module, in which loads are applied in accordance with the ANSI/TIA 222-G standard used in the telecommunications industry. The matrix method was applied, obtaining results for nodal displacement that were compared with the results of physical tests and a metamodel, showing a variation range of 8.44%. In addition, it was shown that a metamodel can be used during the pre-design stage, significantly reducing the time required for analysis.

Keywords : monopole structure; metamodel; flange connection; section inertia; direct matrix.
