To systematically study and determine the failure mechanism of reticulated domes when subjected to impact, ANSYS/LSDYNA was utilized to establish a functional and effective finite-element analysis method for the impact responses of reticulated domes. The impact load characteristics imposed on reticulated domes under three types of failure modes were analyzed, and the peak value and duration time were...
Reticulated domes with substructure system are affected by multiple-support seismic excitations that are spatially correlated and coherent. The influence of the coherency on the seismic responses of such a structure has been investigated but the effect of the spatial correlation and coherency on the responses for the system with different flexibility of the substructure has not been studied. A parametric...
