Abstract
In order to have a good understanding of the failure mechanism of single-layer cylindrical reticulated shells under earthquake motions, two failure modes, that is, dynamic instability and dynamic strength failure, are studied of single-layer cylindrical reticulated shells under earthquake motion. The accumulation of material damages that may accelerate failure of these shells under dynamic actions is considered. The relationships between the structural responses under the ultimate loads are investigated through a systematic simulation study that covers different parameters. A method is proposed for classification of failure modes of the shells, using the fuzzy synthetic evaluation theory and the structural responses of different sample studies. The effectiveness of the proposed method is proved through applications to some examples. Finally, a damage model is established for identification of different structural damage levels and for determination of the ultimate load for strength failure.
