Para ello fue realizado un ensayo experimental en el túnel de viento Joaquim Blessmann, perteneciente a la Universidad Federal de Rio Grande do Sur, para ángulos de ataque entre 0º y 180º con intervalos de 15º. Los resultados obtenidos permiten demostrar la independencia de los coeficientes de forma del número de Reynolds y del contenido de turbulencia del flujo. Se reportan los coeficientes de forma corregidos producto del efecto de bloqueo, obteniéndose los mayores valores en los ángulos de ataque de 0º y 30º.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[ABSTRACT The objective of this paper is to obtain the form coefficients of a two-equal leg angle section, not reflected in the wind load calculation standards used in Cuba for the construction of triangular-based self-supporting telecommunication towers. An experimental test was carried out in the Joaquim Blessmann wind tunnel, belonging to the Federal University of Rio Grande do Sul, for angles of attack between 0º and 180º with intervals of 15º. The obtained results allow to demonstrate the independence of the form coefficients of the Reynolds number and of the turbulent strenght of the flow. The corrected form coefficients are reported as a result of the blockage effect, obtaining the highest values in the attack angles of 0º and 30º.]]></p></abstract>
