Abstract
The two failure modes of shell structure, dynamic instability and intensive destruction, have no distinct boundary on their structural performance; they are fuzzy and are difficult to determine problems. By using the comprehensive evaluation method in fuzzy mathematics and taking the initial imperfection of the structure into consideration, this paper, taking Kiewitt spherical shell as an example, made parameter impact analysis to the structure, and investigated the influence of span ratios, the initial geometric imperfections and bar cross-section of the structure under earthquake failure mode. Ensuring the relations between a variety of response factors of the structure and fuzzy failure modes, the paper established a power failure mode shell structure of fuzzy comprehensive evaluation model and evaluation method, and described the application of the method in the discrimination of failure mode on Kiewitt monolayer Shell with initial defect; the consequences showed that this method can solve the problem of failure mode identification better with more realistic facts and possesses higher accuracy.
