Sensitivity Analysis of Stability Problems of Steel Structures using Shell Finite Elements and Nonlinear Computation Methods

Original language description

The paper analyzes the influence of initial imperfections on the ultimate limit state of a slender strut, applying the ANSYS programme. The geometrical and material nonlinear finite element method was applied for the theoretical analysis. Modelling of the steel structure was performed using SHELL elements. The effect of input imperfections on the load-carrying capacity is evaluated by sensitivity analysis. This paper is devoted to a class of sensitivity analysis techniques that are known as the variance-based methods. Input imperfections are of random origin. The Sobol's sensitivity analysis was used to determine the sensitivity of load-carrying capacity of a strut with respect to the variance of initial imperfections. The sensitivity analysis resultsidentify the imperfections the variability of which can influence the structure reliability. The Latin Hypercube Sampling method was applied for the evaluation of sensitivity indices. The computation model elaborated is unique with regard
