ResumoThe reliability methods allows the evaluation of the limit states violation probability, which are relevant to the structural design.This paper presents an accurate and efficient numerical procedure for evaluating the reliability of steel frames by advanced finite element structural analysis, considering the effects of geometric nonlinearity and semi-rigid connections.The FORM method was used to estimate the probability of failure of performance functions formulated in terms of the ultimate strength and serviceability limit states.The results indicate that the frame reliability is strongly affected by semi-rigid connections and the effects of geometric nonlinearity.
