Resumo(s)
Distributed plasticity Euler-Bernoulli fiber beams are regularly used by
researchers and practitioners to simulate the nonlinear seismic response
of reinforced concrete framed structures. This study presents a sensitivity analysis, combining newly proposed and existing goodness-of-fit
measures, to identify commonly used engineering modeling options
that most critically influence the response accuracy. The dynamic behavior of three distinct structures tested in international blind prediction
challenges is considered. Sensitivity parameters include equivalent viscous damping, element formulation, strain penetration effects, and
material models. The results are critically discussed in light of theoretical
shortcomings of the model assumptions.
