摘要:In this paper, different motivations that justify the interest of stochastic analysis of buckling problems are presented. The work done is based mainly in the application of a discretization method described on a previous article (13). The main part of the work consists of the study of the buckling of a bar with elastic constraints, which are considered random variables. Likewise, for the concrete example of a bar with constant fIexural rigidity, the stochastic trascendent equation is solved using the mentioned discretization method. Finally, other applications of the method to the resolution of stochastic buckling problems, such as the stochastic flexural rigidity and stochastic initial imperfection are pointed out.
