Originální abstrakt

There exist two main categories of structural uncertainties which include spatial correlation, and require the application of random fields. These categories are material and geometrical characteristics. In the presented studies, the random field is applied to the modelling of initial curvature of a slender member axis. Load-carrying capacity of the compress member is calculated by using geometrically nonlinear solution in the programme ANSYS. The solution was carried out by using the beam element BEAM188. The specimen application includes the static random response of an imperfect system generated by geometrical imperfections of member axes with open and hollow cross-sections. The Latin Hypercube Sampling Method was applied.
