Resistance Model Uncertainties in Plane Stress NLFEAs of Reinforced Concrete Systems Subjected to Cyclic Loads

This work describes the resistance model uncertainties in non-linear finite element analyses for reinforced concrete members under cyclic loads for seismic analyses. In detail, several plane stress finite elements analyses using different numerical codes and considering the possible modelling hypotheses are carried out to reproduce the seismic behaviour of various walls experimentally tested. The global resistances achieved from the numerical analyses are compared to the experimental outcomes to assess the influence of the model uncertainties.
