Probabilistic study about uncertainties in predicting sheer beam cracking and failure
Original language description
Deep beam with very large dimensions (span of 21 m, height of 4 m) was investigated experimentally at University of Toronto, Canada. A competition for blind prediction of the beam failure was organized with more than 60 participants worldwide. The shear behavior, cracking and strength of the beam was significantly affected by the large beam size. The best results were achieved and submitted by Červenka Consulting with ATENA deterministic numerical analysis based on nonlinear constitutive model of concrete using fracture mechanics. After the predictive contest authors performed several studies about input parameters of the material models, FE-mesh size etc. and their influence to the beam capacity, response and cracking. An advanced probabilistic analysis based on LHS method with random fields and random variables approaches has been consequently applied and evaluated.
