Shear Failure of Very Large Concrete Beam: Nonlinear, probabilistic and semi-probabilistic modelling

Original language description

The shear capacity of very large concrete beams was simulated using numerical analysis based on advanced nonlinear constitutive model of concrete using fracture mechanics. A very good agreement between experiments and computational modelling in the sense of load-deflection curve and crack patterns has been obtained. A study is focused on shear capacity of the beam influenced by the uncertainty of material parameters and their spatial distribution using advanced probabilistic methods, namely random fields and random variables was additionally performed. The shear strength of concrete beams was significantly affected by its large size, where spatial variability of material parameters played important role. Moreover, once the statistical moments of resistance were obtained by advanced probabilistic approach, ultimate shear capacity satisfying given safety requirements was determined by several semi-probabilistic and normative methods. Results from this study and consequent assessment of model uncertainty are presented and summarized in the last part of this study.
