摘要：
The finite element analysis model of single-layer cylindrical aluminum alloy reticulated shell structures was established in ABAQUS. The whole process of dynamic response of the reticulated shell structures under severe earthquake was analyzed by using the incremental dynamic analysis (IDA) method. The failure modes of single-layer cylindrical aluminum alloy reticulated shell structures under severe earthquake were obtained. Based on the fuzzy mathematics theory, the failure criterion of single-layer cylindrical aluminum alloy reticulated shell structures under severe earthquake was proposed. Based on the large-scale parameter analysis, the damage degree classification of aluminum alloy reticulated shell structures was defined and identified. Through random sampling, a certain number of structure-earthquake samples were selected to carry out the seismic vulnerability analysis of aluminum alloy reticulated shell structures. Through regression analysis, the seismic vulnerability function was established to obtain the seismic vulnerability curves of single-layer cylindrical aluminum alloy reticulated shells. The results show that the aluminum alloy reticulated shells has good seismic performance through the seismic vulnerability analysis, and the probability of remaining basically intact or only slightly damaged under severe earthquake is large. © 2020, Editorial Office of Journal of Building Structures.
