| Abstract: | In this paper, Starting from the deflection curve of a beam with random stiffness, the analytic expressions to study the beam with random stiffness are given, in which the local average method is joined with the difference method of the second order. Authors in this paper have tested the accuracy of the local average method and improved some of the defaults in stochastic analysis for a beam. |
