- W2891813890 abstract "espanolEl presente trabajo de investigacion estudia el comportamiento de perfiles estructurales de acero de pared delgada, de produccion nacional venezolana Conduven ECO, de seccion transversal cuadrada, construidos en forma de viga tipo cantilever, bajo los efectos de fatiga de ultra-bajo ciclaje. Se realizaron ensayos experimentales aplicandose historias de desplazamientos ciclicos, con baja velocidad y actuando en un rango que va desde el esfuerzo cedente hasta el esfuerzo ultimo del elemento, obteniendo una degradacion de la capacidad resistente de los perfiles mediante el fenomeno de fatiga de ultra-bajo ciclaje, inducido por la aparicion de la falla por pandeo local en los elementos ensayados. EnglishThe present work of investigation studies the behavior of steel structural sections of thin wall, made in Venezuelan Conduven ECO, of square cross section, constructed in the form of a cantilever type beam, under the effects of fatigue of ultra-low cycling. Experimental tests were carried out applying histories of cyclic displacements, with low speed and acting in a range that goes from the yielding effort to the last effort of the element, obtaining a degradation of the resistant capacity of the elements through the phenomenon of fatigue of ultra-low Cycling, induced by the appearance of the fault by local buckling in the elements tested." @default.
