Non-linear analyses of slender RC members: on the assessment of global factors for safety verification

The aim of thi study is to present an overview and a comparison of the methods finalised to derive global safety factors for non-linear analysis of slender RC members. In detail, a set of 40 experimental results on reinforced concrete columns is illustrated and described in its main aspects. Several non-linear numerical models have been realized using fiber approach as modelling hypothesis. Then, proper proabilstic models have been defined with the aim to include geometric, material and model uncertainties to perform a probabilistic analysis in terms of global resistance. Successively, the outcomes from the probabilistic analysis are used to define the global safy factors for safety verifications of slender RC members. Finally, different methods are compared highliting the corresponding differences and limits.
