TL;DR: In this article, the results of experimental research of material and geometrical characteristics of Czech steel are given in the present paper, where yield strength, tensile strength and ductility were evaluated statistically.

TL;DR: It is stated that before long the decision-making in civil engineering may face several methodological problems: the need to combine fuzzy and probabilistic representations of uncertainties in one decision- making matrix, the necessity to extend a global sensitivity analysis to all input elements of a MCDM problem with uncertainties, and an application of M CDM methods in the areas of civil engineering where decision- Making under uncertainty is presently not common.

TL;DR: In this article, the experimental results of material and geometrical characteristics of Czech steel are given in the presented paper, where measurements are carried out for the yield strength of plates made of steel grade S355.

TL;DR: In this paper, the authors present the sensitivity and statistical analyses of the load-carrying capacity of a steel portal frame, and apply the Sobol sensitivity analysis to identify the dominant input random imperfections and their higher order interaction effects on the load carrying capacity.

TL;DR: In this article, a hot-rolled steel I-beam subjected to lateral-torsional buckling due to bending moment is examined and a non-linear finite element model and numerical approximation and simulation methods used for the global sensitivity analysis of the static resistance of a beam under major axis bending.
