Global non-linear numerical analysis of slender reinforced concrete members including aleatory uncertainties

This investigation aims to define the structural reliability of slender reinforced concrete members through non-linear numerical analysis adopting the global resistance format approach. An experimental database of 40 tests on slender columns is adopted. The laboratory tests have been reproduced by means of numerical models able to account for geometric and materials non-linerarities. Then, the calibrated models have been used to perform probabilistic analysis of structural resistance and the global resistance safety factors have been derived. Finally, the design vaulues of structural resistance are compared to the ones derived by the application of safety formats based on global resistance method.
