Original Abstract

Different approaches for determining the degree of uncertainty in models for the analysis of the serviceability limit state of building structures are described. An example of fuzzy and stochastic analysis of the uncertainty of deformation of a load bearing steel truss structure is presented. The relationships between the force acting on the structure and the elastic deformation of the structure caused by this force are studied using numerical simulations on the computer. The static response and elastic deformation are evaluated using linear and geometrically nonlinear models. It is proven in the article that small uncertainties in the initial geometric imperfections can lead to relatively large uncertainty in the response of the model, on the basis of which the safety and reliability of the structure are assessed.
