The purpose of this paper is to propose the analytical method of reliability for redundant ductile portal frames. The relation between a demarcating correlation coefficient in PNET (Probabilistic Network Evaluation Technique) method and some analytical parameters such as correlation coefficient in uncertain factors, load ratio, member reliability, are clarified by the numerical calculation on reliability of some types of portal frames. Based on the case study, we propose the method for calculation of the global failure probabilities of redundant ductile portal frames. The proposed method requires no consideration of the simultaneous failure probability of failure modes because of the selection of majour failure modes which should be evaluated for each type of failure mechanism. The efficiency of the proposed method are shown through comparison with some other evaluating methods for the global failure probability.
