A large beam tested at Toronto University for a prediction contest was simulated by the authors using a nonlinear finite element code. Their entry was chosen as the overall winner of the prediction contest and was a motivation for this case study. The crack propagation was modeled by a smeared crack approach and a fracture mechanics-based cohesive crack model. The paper discusses the model sensitivity to mesh sizes and fracture parameters. A parameter study was performed to examine the model
