Abstract
In this paper, a concept for safety and durability assessment of reinforced concrete structures is presented. It is based on a multilevel modeling approach, where three different models are combined using simple linear elastic beam models for the reinforcement design, low fidelity nonlinear finite element models to compute the deformation at the full structural scale and finally high fidelity nonlinear finite element models to compute the crack widths at critical hot spots of the structure. The uncertainty of structural parameters is quantified by means of polymorphic uncertainty models combining stochastic and non-stochastic approaches. The multilevel approach is applied to the safety assessment and the crack widths prediction of a reinforced concrete beam structure. Copyright © 2019 European Safety and Reliability Association.
