Abstract (EN): Performance-based earthquake engineering methods rely heavily on nonlinear dynamic analysis to determine structural performance. Given the significant number of existing structural and material modelling approaches, the epistemic uncertainty associated to such strategies requires adequate quantification. In this context, the proposed study addresses the quantification of the uncertainty associated to different modelling choices at the member section level. The study analyses the performance of 56 modelling combinations for the numerical simulation of moment-curvatures evolutions obtained from experimental tests on reinforced concrete columns. To determine the performance of the modelling approaches, the results are analysed for three behaviour ranges.
