Estudio de la velocidad básica de viento en Ecuador, como criterio de diseño para torres de telecomunicaciones.

Abstract

In this study, a monopole type structure was compared for 2 different design scenarios, the first design scenario with an arbitrary basic wind speed equal to 120km / h and the second with a basic wind speed defined by a statistical analysis method. A first aspect of the study considered the review of the parameters of the TIA-222- G standard for the calculation of wind forces, the specifications of the NEC-15 standard mainly for determining seismic loads and the AISC360-16 standard for the design steel parts, the Binomial statistical method for calculating wind speeds was also revised. Then, using information from INAMHI meteorological yearbooks and employing the binomial method, the wind speed of the structure's site was determined. After this, wind and earthquake loads were determined for both design scenarios, which were entered into the SAP2000 software as part of the modeling of the structures, to then proceed to the design of optimal sections for each monopole. Finally, the weight comparison of both structures was carried out, it is concluded that there is a 29% optimization of steel from one monopole compared against the other.
