Reliability Assessment of Design Formulas for Shear Capacity of Glass Fibre Reinforced Polymers Concrete Elements

Abstract:

Shear strength probabilistic assessment of concrete members with glass fibre reinforced polymers (GFRP) is performed in the paper. The aim of the analysis performed is to verify the existing code analytical formulas for shear strength calculation using stochastic models, to perform uncertainty propagation, sensitivity analysis and model uncertainty assessment. The study introduces a probabilistic framework that incorporates both model uncertainty and stochastic variability of input parameters into the assessment of shear resistance. The code models of Eurocode 2, ACI 440 and the fib Model Code 2010 are examined with respect to uncertainties involved and the reliability of the design value determination.
