In this paper, seismic behavior of Kiewitt-Sunflower single layer spherical reticulated shells is examined within the time history method, based on our proposed damage constitutive model for thin-walled circular steel tubes. According to a large number of numerical examples, the failure mode of this kind of single layer spherical reticulated shell in the case of earthquake is figured out. In addition, the effect of the damage accumulation, rise-span ratio, initial geometric imperfection, types of seismic wave and amplitude modulation ratio on the dynamic response of the shell structure is explored. Finally, a structural damage factor is proposed and it has a good match with the numerical results, which is productive to assess the damage and failure behavior of such structures suffering the earthquake and post-earthquake.
