Numerical Investigation on the Reticulated Domes Subjected to the Multi-Point Impact

Abstract:

In the present paper, FE model of the single-layer Kiewitt-8 reticulated domes with a span of 60m was built with using of ANSYS/AUTODYN. The dynamic response of the reticulated domes against the multi-point impact was investigated, where a special impactor was involved. Based on the simulation results, four damage modes were concluded，which are local damage, global collapse, local damage with punching plug, punching plug respectively. It was indicated that the initial kinetic energy of the impactor have a close correlation with the damage mode. Furthermore, the characteristics of dynamic response for each damage mode were shown.
