This paper presents the study on the influence of substructures on the failure behavior of steel reticulated domes subjected to the severe earthquake. The full-range dynamic response analysis method is applied to investigate the failure characteristics of single-layer steel reticulated domes with substructures subjected to the severe earthquake. The natural vibration properties are studied. Two typical failure modes of steel reticulated domes with substructures are illustrated according to the stiffness of substructures. Failure criterion is proposed to estimate the ultimate load strength for single-layer steel reticulated domes. It is observed that the substructure has great influence on the failure characteristics and the ultimate load strength of steel reticulated domes subjected to the severe earthquake. It is necessary to take substructure into consideration in analysis and design stage.
