Uncertainty In The Simulation Of Concrete Fracture And Comparison With Blind Competitions

Original language description

Fracture mechanics based nonlinear analysis of reinforced concrete structures is becoming a standard engineering tool for the assessment of existing structures as well as for the design of new structures. This development is supported by the introduction of new safety formats for nonlinear analysis in the fib model code 2010, which are being implemented in the new version of Eurocodes prEN 1992 1 1:2022. An important aspect is the evaluation and treatment of all uncertainties involved. The paper focuses on the treatment of model uncertainty. Interesting insight into the uncertainty of fracture mechanics based modelling can be obtained by studying several recent blind prediction competitions. The blind predictions are useful for the assessment of the robustness and reliability of existing models or software tools. Their specifics and limits will be demonstrated using five recent prediction competitions. The main deficiency is that material uncertainty is usually not addressed; therefore, the most accurate predictions are usually pure lucky shots.
