SENSITIVITY ANALYSIS OF STABILITY PROBLEMS OF STEEL COLUMNS USING SHELL FINITE ELEMENTS AND NONLINEAR COMPUTATION METHODS
Kala Z., Kala J.
pages 271 - 274, full text

The paper analyzes the influence of initial imperfections on the load-carrying capacity 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 Sobol’ sensitivity analysis. The computation model elaborated is unique with regard to its numerically demanding character. The Latin Hypercube Sampling method was applied for the evaluation of sensitivity indices.
