Model Uncertainties in Resistances of Steel Members

Popis výsledku v původním jazyce

Resistance of steel structures is primarily dependent on material properties, geometry and uncertainties related to an applied model. While materials and geometry can be relatively well described, the uncertainties in resistance models are often insufficiently considered in reliability analysis. In many cases significant efforts are spent to improve resistance models and reduce the uncertainty associated with outcomes of the model. However, these achievements are then inadequately reflected in the values of partial factors. That is why the present paper clarifies a model uncertainty, its quantification and derivation of appropriate partial factors. Initially a general concept of the model uncertainty is proposed. Statistical characteristics of the uncertainties in resistance of steel members are then provided. The partial factors for the model uncertainties are derived using a semi-probabilistic approach to facilitate practical applications.
