Algunos investigadores opinan que estas pérdidas pudieran se ocasionadas por insuficiencias en las normativas para el cálculo de las edificaciones ante este tipo de cargas. En este artículo se comparan los coeficientes de presión de las cubiertas de varias edificaciones bajas que han sido ensayadas tanto en túneles de viento como por métodos numéricos (modelación computacional de fluidos) por diversos investigadores, con los coeficientes que resultarían de aplicar el Eurocódigo EN1991-1-4 sobre esas mismas estructuras. Esta investigación tiene el propósito de identificar las posibles discrepancias entre el Eurocódigo EN1991-1-4 y los ensayos experimentales, como consecuencia de la no consideración de las variaciones de la intensidad de turbulencia y de la inclinación de la cubierta en la obtención de los coeficientes de presión en la normativa. Del análisis de resultados se obtuvo que la aplicación del Eurocódigo EN1991-1-4 conduce a la subestimación de la carga de viento en la mayor parte de la cubierta, mientras que en la esquina correspondiente al borde de ataque del viento, la carga obtenida es mayor que la resultante de los ensayos.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract Every year, failures in the roofs of low buildings due to wind action occur. Some researchers believe that these losses could be caused by inadequacies in the regulations for buildings design under this type of loads. This article compares the pressure coefficients of roofs of various low buildings that have been tested, both in wind tunnels and by numerical methods (computational fluid modeling), by various researchers, with the coefficients result from applying the Eurocode EN1991- 1-4 on those structures. The purpose of this investigation is to identify possible discrepancies between the Eurocode EN1991-1-4 and the experimental tests, as a consequence of neglecting the variations in the intensity of turbulence and the roof slope in obtaining the pressure coefficients. From the analysis of results, it was found that the application of Eurocode EN1991-1-4 leads to an underestimation of the wind load in most of the roof, while in the corner corresponding to the leading edge of the wind, the load obtained is greater than that resulting from tests.]]></p></abstract>
