| Abstract: |
| In the non-probabilistic framework, reliability of structural systems is depended upon the worst failure mode, which has the least reliability indexing all possible failure modes of the structures. Therefore, the identification of the worst failure mode and the establishment of corresponding limit state equations are the critical problems of reliability analysis of the nonprobabilistic structural systems. Considering the uncertainties in structural parameters, strength and applied loads, an optimal criterion enumerating the main failure modes of nonprobabilistic structural systems are presented, which is based on the optimal criterion method used in the probabilistic reliability theory. The method able to ensure the worst failure mode included in a few enumerated main failure modes. The limit state equations of main failure modes are formulated by the increment interval load method. Two numerical examples illustrate usefulness and effectiveness of the proposed procedure. |
