摘要：
To study whether or not structural responses of double-layer reticulated domes was sensitive to sequence earthquake to avoid structure collapse under aftershocks, a structure's finite element model was established based on the finite element software ABAQUS. Data of main shock and aftershock responses to sequence earthquake in database of the pacific earthquake engineering research center (PEER) were selected to collect 342 groups of main shock and aftershock acceleration response time histories data. The dynamic time history analysis method in full load domain was adopted to obtain variation laws of structural characteristic responses with changes of acceleration amplitude under various sequence earthquakes. 4 effect levels on reticulated shell structures' multiple seismic responses were classified and defined. Then, statistic analysis was done for a lot of example results to obtain the relation between reticulated shells' characteristic responses of maximum nodal displacement, proportion of yield members and structural damage factor when main shock was over and structures' anti-aftershock ability. Finally, the proportion of yield members was taken as the index to measure double-layer reticulated domes' anti-aftershock ability, and sensitive limit values of proportion of yield members for double-layer reticulated domes with different spans were given. The study results provided a reference for aseismic design and aseismic performance evaluation of reticulated shell structures. © 2020, Editorial Office of Journal of Vibration and Shock.
