Experimental analysis of tubular wall-threaded sections submitted to ultra-low cycling fatigue

Experimental analysis of tubular wall-threaded sections submitted to ultra-low cycling fatigue

The 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 applyi...

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. El presente trabajo de investigación estudia el comportamiento de perfiles estructurales de acero de pared delgada, de producción nacional venezolana Conduven ECO, de sección transversal cuadrada, construidos en forma de viga tipo cantiléver, bajo los efectos de fatiga de ultra-bajo ciclaje. Se realizaron ensayos experimentales aplicándose historias de desplazamientos cíclicos, con baja velocidad y actuando en un rango que va desde el esfuerzo cedente hasta el esfuerzo último del elemento, obteniendo una degradación de la capacidad resistente de los perfiles mediante el fenómeno de fatiga de ultra-bajo ciclaje, inducido por la aparición de la falla por pandeo local en los elementos ensayados.
