Abstract

Este trabajo está relacionado con el estudio del comportamiento de estructuras de paredes delgadas sometidas a presión
externa, cuando aparecen imperfecciones geométricas, inherentes a los procesos de fabricación, que afectan los valores de
las cargas críticas. En el mismo se describen comportamientos pos críticos típicos y su importancia en el estudio de los
efectos de estas imperfecciones, así como formulaciones aproximadas, tomando en consideración la necesidad del
conocimiento de las posibles trayectorias de equilibrio por parte del ingeniero en el análisis y toma de decisiones acerca de
una estructura.


Palabras claves: Estructura, bóveda, estabilidad, fallas estructurales, trayectorias de equilibrio.

Abstract
This work deals with the study of the behavior of thin walled structures external pressure, when in the same appear geometric
imperfections that are inherent to the process of manufacturing and affect the values of critical loads. In the same, post critical
typical behaviors and its importance in the study of the effects of the geometric imperfections are described, as well as
approximate formulations taking in consideration the possible trajectories of equilibrium in the structure analysis re.


Key words: structures, shells, stability, structural failures, trajectories of equilibrium.
