‘In structural system, a certain amount of uncertainties always persists in material properties, geometric parameters and applied loads. In this study, the structure is designed to withstand theuncertainties which are caused by either measurement inaccuracy or system complexity. Randomstructures are modelled by using ANSYS probabilistic design module. It can be applied easily to anystructural system with random parameters. The aim of this paper is to make optimal design for the beamwith random input variables due to width and height and response parameters due to displacements andstresses. The probabilistic design is also carried out with ANSYS APDL and then the optimal design issequentially solved. As the total volume of beam, stresses and displacements at the beam are treated asrandom parameters, the numerical results are obtained.'
