Análisis técnico comparativo de una torre triangular autosoportada de 42 m. de altura en el cantón Mocha, provincia de Tungurahua; utilizando la norma ANSI/TIA 222-G-2005 y ANSI/TIA 222-H-2017

Abstract

Over the years, telecommunication companies in Ecuador have experienced dizzying growth; this is due to the increasing demand for internet and telephony services in areas where coverage is unlimited. To meet these needs, companies are committed to building the best self-sustainable tower designs. Therefore, the objective of this academic paper is to analyze the real behavior of this structure; through a comparative technical analysis of a 42 m. high self-supported tower, using the ANSI TIA 222-G standard and its updated version ANSI TIA 222-H; for which two modeling’s were generated, one for each standard. This allowed determining aspects of the structure such as: load capacity, structural stability and resistance to environmental forces such as seismic and wind; this last factor is significant, since it is the main cause of failure of this type of structures. It is important to note that the same geometry, configuration and material were maintained in both structures in order to make an accurate comparison. The results obtained indicated that the ANSI TIA 222-H criterion is optimal for the design and construction of the tower studied; this criterion allows a minimum consumption of material and a greater resistance to the acting loads; furthermore, the results revealed that the ANSI TIA 222-H Standard reduces forces, deflections, reactions and moments by more than 50% compared to the ANSI TIA 222-G Standard.
