Model uncertainties in numerical simulations of reinforced concrete structures
Original language description
Numerical simulation based on the nonlinear fine element analysis requires a global safety format, which includes a model uncertainty. A general method for assessment of a global safety factor of model uncertainty is proposed for a particular resistance model. A set of 33 laboratory tests of reinforced concrete elements published by other authors is used for the model validation. It covers a wide range of failure models from brittle to ductile, and the member cross section size range from 0.1 to 4 m. The numerical model used for simulation is the fracture-plastic constitutive model for concrete developed by the authors and implemented in the nonlinear finite element analysis in a commercial software.
